# Flatpak Command Reference

Version 1.16.6

### Important

The command reference is generated from the flatpak repo; see https://github.com/flatpak/flatpak/tree/main/doc

Flatpak comes with a rich commandline interface.

## Executables

## Name

flatpak — Build, install and run applications and runtimes

## Synopsis

`flatpak` [OPTION...] {COMMAND}

## Description

Flatpak is a tool for managing applications and the runtimes they use. In the Flatpak model, applications can be built and distributed independently from the host system they are used on, and they are isolated from the host system ('sandboxed') to some degree, at runtime.

Flatpak can operate in system-wide or per-user mode. The system-wide data (runtimes, applications and configuration) is located in `$prefix/var/lib/flatpak/`, and the per-user data is in `$HOME/.local/share/flatpak/`. Below these locations, there is a local repository in the `repo/` subdirectory and installed runtimes and applications are in the corresponding `runtime/` and `app/` subdirectories.

System-wide remotes can be statically preconfigured by dropping flatpakrepo(5) files into `/usr/share/flatpak/remotes.d/` and `/etc/flatpak/remotes.d/`. If a file with the same name exists in both, the file under `/etc` will take precedence.

In addition to the system-wide installation in `$prefix/var/lib/flatpak/`, which is always considered the default one unless overridden, more system-wide installations can be defined via configuration files in `/etc/flatpak/installations.d/`, which must define at least the id of the installation and the absolute path to it. Other optional parameters like DisplayName , Priority or StorageType are also supported.

Flatpak uses OSTree to distribute and deploy data. The repositories it uses are OSTree repositories and can be manipulated with the ostree utility. Installed runtimes and applications are OSTree checkouts.

Basic commands for building flatpaks such as build-init, build and build-finish are included in the flatpak utility. For higher-level build support, see the separate flatpak-builder(1) tool.

Flatpak supports installing from sideload repos. These are partial copies of a repository (generated by flatpak create-usb) that are used as an installation source when offline (and online as a performance improvement). Such repositories are configured by creating symlinks to the sideload sources in the `sideload-repos` subdirectory of the installation directory (i.e. typically `/var/lib/flatpak/sideload-repos` or `~/.local/share/flatpak/sideload-repos`). Additionally symlinks can be created in `/run/flatpak/sideload-repos` which is a better location for non-persistent sources (as it is cleared on reboot). These symlinks can point to either the directory given to flatpak create-usb which by default writes to the subpath `.ostree/repo`, or directly to an ostree repo.

## Options

The following global options are understood. Individual commands have their own options.

`-h`, `--help`

  Show help options and exit.

`-v`, `--verbose`

  Show debug information during command processing. Use -vv for more detail.

## Environment

Besides standard environment variables such as `XDG_DATA_DIRS` and `XDG_DATA_HOME`, flatpak consults some of its own.

`FLATPAK_BINARY`

  Path to the flatpak executable that will be written into exported `.desktop` files and scripts when an app is installed. The default is `/usr/bin/flatpak`, unless overridden at build time by `--bindir`.

`FLATPAK_BWRAP`

  Path to the bwrap(1) executable that will be used to create the sandbox. Depending on how Flatpak was configured at build-time, the default is either to search the `PATH`, or use a vendored copy which is normally installed as `/usr/libexec/flatpak-bwrap`.

`FLATPAK_CONFIG_DIR`

  The location of flatpak site configuration. If this is not set, `/etc/flatpak` is used (unless overridden at build time by --sysconfdir).

`FLATPAK_DATA_DIR`

  The location of Flatpak's OS-level defaults and integration hooks. If this is not set, `/usr/share/flatpak` is used, unless overridden at build time by `--datadir`.

`FLATPAK_DBUSPROXY`

  Path to the xdg-dbus-proxy(1) executable that will be used to filter D-Bus traffic between the sandbox and the host system. Depending on how Flatpak was configured at build-time, the default is either to search the `PATH`, or use a vendored copy which is normally installed as `/usr/libexec/flatpak-dbus-proxy`.

`FLATPAK_DOWNLOAD_TMPDIR`

  Path to a directory that will be used temporarily when downloading OCI layers, and potentially for other downloads in future. The standard `TMPDIR` is not used for this, because Flatpak apps are frequently too large to fit on a tmpfs.

`FLATPAK_FANCY_OUTPUT`

  May be set to `0` to avoid fancy formatting when outputting to a terminal. This feature is also disabled automatically when standard output is not a terminal, or when `G_MESSAGES_DEBUG` is set.

`FLATPAK_FORCE_TEXT_AUTH`

  May be set to `1` to force use of a simple built-in polkit(8) agent when authentication is required to modify the system-wide installation. By default, the desktop environment's polkit agent is used, if one is available, usually resulting in a graphical prompt.

`FLATPAK_GL_DRIVERS`

  A colon-separated list of graphics driver extensions to try to use for OpenGL, Vulkan and similar APIs, most-preferred first. The default is to select a graphics driver automatically. Values in this list match the last dot-separated component of the names of extensions with the `active-gl-driver` condition. Typical values are `default`, `mesa-git` or `nvidia-550-120` (replacing the version number by the major and minor version of the `nvidia` kernel module).

`FLATPAK_RUN_DIR`

  The location of flatpak runtime global files. If this is not set, `/run/flatpak` is used.

`FLATPAK_SYSTEM_CACHE_DIR`

  The location where temporary child repositories will be created during pulls into the system-wide installation. If this is not set, a directory in `/var/tmp/` is used. This is useful because it is more likely to be on the same filesystem as the system repository (thus increasing the chances for e.g. reflink copying), and we can avoid filling the user's home directory with temporary data.

`FLATPAK_SYSTEM_DIR`

  The location of the default system-wide installation. If this is not set, `/var/lib/flatpak` is used (unless overridden at build time by `--localstatedir` or `-Dsystem_install_dir`).

`FLATPAK_TTY_PROGRESS`

  May be set to `1` to enable reporting machine-readable progress to the terminal. This feature is not currently enabled by default because it uses the OSC 9;4 sequence, which some terminal emulators interpret as a popup notification.

`FLATPAK_USER_DIR`

  The location of the per-user installation. If this is not set, `$XDG_DATA_HOME/flatpak` is used.

## Commands

## Name

flatpak-build-bundle — Create a single-file bundle from a local repository

## Synopsis

`flatpak build-bundle` [OPTION...] LOCATION FILENAME NAME [BRANCH]

## Description

Creates a single-file named FILENAME for the application (or runtime) named NAME in the repository at LOCATION . If a BRANCH is specified, this branch of the application is used.

The collection ID set on the repository at LOCATION (if set) will be used for the bundle.

Unless `--oci` is used, the format of the bundle file is that of an ostree static delta (against an empty base) with some flatpak specific metadata for the application icons and appdata.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--runtime`

  Export a runtime instead of an application.

`--arch=ARCH`

  The arch to create a bundle for. See flatpak --supported-arches for architectures supported by the host.

`--repo-url=URL`

  The URL for the repository from which the application can be updated. Installing the bundle will automatically configure a remote for this URL.

`--runtime-repo=URL`

  The URL for a `.flatpakrepo` file that contains the information about the repository that supplies the runtimes required by the app.

`--gpg-keys=FILE`

  Add the GPG key from FILE (use - for stdin).

`--gpg-homedir=PATH`

  GPG Homedir to use when looking for keyrings.

`--from-commit=COMMIT`

  The OSTree commit to create a delta bundle from.

`--oci`

  Export to an OCI image instead of a Flatpak bundle.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Examples

$ flatpak build-bundle /var/lib/flatpak/repo gnome-calculator.flatpak org.gnome.Calculator stable

$ flatpak build-bundle ~/.local/share/flatpak/repo gnome-calculator.flatpak org.gnome.Calculator stable

## See also

ostree(1), flatpak(1), flatpak-build-init(1), flatpak-build(1), flatpak-build-finish(1), flatpak-build-import-bundle(1), flatpak-build-update-repo(1)

## Name

flatpak-build-commit-from — Create new commits based on existing one (possibly from another repository)

## Synopsis

`flatpak build-commit-from` [OPTION...] DST-REPO DST-REF...

## Description

Creates new commits on the DST-REF branch in the DST-REPO , with the contents (and most of the metadata) taken from another branch, either from another repo, or from another branch in the same repository.

The collection ID set on DST-REPO (if set) will be used for the newly created commits.

This command is very useful when you want to maintain a branch with a clean history that has no unsigned or broken commits. For instance, you can import the head from a different repository from an automatic builder when you've verified that it worked. The new commit will have no parents or signatures from the autobuilder, and can be properly signed with the official key.

Any deltas that affect the original commit and that match parent commits in the destination repository are copied and rewritten for the new commit id.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--src-repo=SRC-REPO`

  The (local) repository to pull the source branch from. Defaults to the destination repository.

`--src-ref=SRC-REF`

  The branch to use as the source for the new commit. Defaults to the same as the destination ref, which is useful only if a different source repo has been specified.

`--extra-collection-id=COLLECTION-ID`

  Add an extra collection-ref binding for this collection, in addition to whatever would normally be added due to the destination repository collection id. This option can be used multiple times.

`--subset=SUBSET`

  Mark the commit to be included in the named subset. This will cause the commit to be put in the named subset summary (in addition to the main one), allowing users to see only this subset instead of the whole repo.

`--untrusted`

  The source repostory is not trusted, all objects are copied (not hardlinked) and all checksums are verified.

`-s`, `--subject=SUBJECT`

  One line subject for the commit message. If not specified, will be taken from the source commit.

`-b`, `--body=BODY`

  Full description for the commit message. If not specified, will be taken from the source commit.

`--update-appstream`

  Update the appstream branch after the build.

`--no-update-summary`

  Don't update the summary file after the new commit is added. This means the repository will not be useful for serving over http until build-update-repo has been run. This is useful is you want to do multiple repo operations before finally updating the summary.

`--force`

  Create new commit even if the content didn't change from the existing branch head.

`--disable-fsync`

  Don't fsync when writing to the repository. This can result in data loss in exceptional situations, but can improve performance when working with temporary or test repositories.

`--gpg-sign=KEYID`

  Sign the commit with this GPG key. This option can be used multiple times.

`--gpg-homedir=PATH`

  GPG Homedir to use when looking for keyrings

`--end-of-life=REASON`

  Mark build as end-of-life

`--end-of-life-rebase=OLDID=NEWID`

  Mark new refs as end-of-life. Unlike `--end-of-life`, this one takes an ID that supersedes the current one. By the user's request, the application data may be preserved for the new application. Note, this is actually a prefix match, so if you say org.the.app=org.new.app, then something like org.the.app.Locale will be rebased to org.new.app.Locale.

`--timestamp=TIMESTAMP`

  Override the timestamp of the commit. Use an ISO 8601 formatted date, or NOW for the current time

`--disable-fsync`

  Don't fsync when writing to the repository. This can result in data loss in exceptional situations, but can improve performance when working with temporary or test repositories.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Examples

To revert a commit to the commit before:

$ flatpak build-commit-from --timestamp=NOW --src-ref=app/org.gnome.gedit/x86_64/master^ repo app/org.gnome.gedit/x86_64/master

## Name

flatpak-build-export — Create a repository from a build directory

## Synopsis

`flatpak build-export` [OPTION...] LOCATION DIRECTORY [BRANCH]

## Description

Creates or updates a repository with an application build. LOCATION is the location of the repository. DIRECTORY must be a finalized build directory. If BRANCH is not specified, it is assumed to be "master".

If LOCATION exists, it is assumed to be an OSTree repository, otherwise a new OSTree repository is created at this location. The repository can be inspected with the ostree tool.

The contents of DIRECTORY are committed on the branch with name `app/APPNAME/ARCH/BRANCH`, where ARCH is the architecture of the runtime that the application is using. A commit filter is used to enforce that only the contents of the `files/` and `export/` subdirectories and the `metadata` file are included in the commit, anything else is ignored.

When exporting a flatpak to be published to the internet, `--collection-id=COLLECTION-ID` should be specified as a globally unique reverse DNS value to identify the collection of flatpaks this will be added to. Setting a globally unique collection ID allows the apps in the repository to be shared over peer to peer systems without needing further configuration.

The build-update-repo command should be used to update repository metadata whenever application builds are added to a repository.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-s`, `--subject=SUBJECT`

  One line subject for the commit message.

`-b`, `--body=BODY`

  Full description for the commit message.

`--collection-id=COLLECTION-ID`

  Set as the collection ID of the repository. Setting a globally unique collection ID allows the apps in the repository to be shared over peer to peer systems without needing further configuration. If exporting to an existing repository, the collection ID must match the existing configured collection ID for that repository.

`--subset=SUBSET`

  Mark the commit to be included in the named subset. This will cause the commit to be put in the named subset summary (in addition to the main one), allowing users to see only this subset instead of the whole repo.

`--arch=ARCH`

  Specify the architecture component of the branch to export. Only host compatible architectures can be specified; see flatpak --supported-arches for valid values.

`--exclude=PATTERN`

  Exclude files matching PATTERN from the commit. This option can be used multiple times.

`--include=PATTERN`

  Don't exclude files matching PATTERN from the commit, even if they match the `--exclude` patterns. This option can be used multiple times.

`--metadata=FILENAME`

  Use the specified filename as metadata in the exported app instead of the default file (called `metadata`). This is useful if you want to commit multiple things from a single build tree, typically used in combination with `--files` and `--exclude`.

`--files=SUBDIR`

  Use the files in the specified subdirectory as the file contents, rather than the regular `files` directory.

`--timestamp=DATE`

  Use the specified ISO 8601 formatted date or NOW, for the current time, in the commit metadata and, if `--update-appstream` is used, the appstream data.

`--end-of-life=REASON`

  Mark the build as end-of-life. REASON is a message that may be shown to users installing this build.

`--end-of-life-rebase=ID`

  Mark the build as end-of-life. Unlike `--end-of-life`, this one takes an ID that supersedes the current one. By the user's request, the application data may be preserved for the new application.

`--disable-fsync`

  Don't fsync when writing to the repository. This can result in data loss in exceptional situations, but can improve performance when working with temporary or test repositories.

`--update-appstream`

  Update the appstream branch after the build.

`--no-update-summary`

  Don't update the summary file after the new commit is added. This means the repository will not be useful for serving over http until build-update-repo has been run. This is useful is you want to do multiple repo operations before finally updating the summary.

`--gpg-sign=KEYID`

  Sign the commit with this GPG key. This option can be used multiple times.

`--gpg-homedir=PATH`

  GPG Homedir to use when looking for keyrings

`-r`, `--runtime`

  Export a runtime instead of an app (this uses the usr subdir as files).

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Name

flatpak-build-finish — Finalize a build directory

## Synopsis

`flatpak build-finish` [OPTION...] DIRECTORY

## Description

Finalizes a build directory, to prepare it for exporting. DIRECTORY is the name of the directory.

The result of this command is that desktop files, icons, D-Bus service files, and AppStream metainfo files from the `files` subdirectory are copied to a new `export` subdirectory. In the `metadata` file, the command key is set in the [Application] group, and the supported keys in the [Environment] group are set according to the options.

As part of finalization you can also specify permissions that the app needs, using the various options specified below. Additionally during finalization the permissions from the runtime are inherited into the app unless you specify `--no-inherit-permissions`

You should review the exported files and the application metadata before creating and distributing an application bundle.

It is an error to run build-finish on a directory that has not been initialized as a build directory, or has already been finalized.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--command=COMMAND`

  The command to use. If this option is not specified, the first executable found in `files/bin` is used.

  Note that the command is used when the application is run via flatpak run, and does not affect what gets executed when the application is run in other ways, e.g. via the desktop file or D-Bus activation.

`--require-version=MAJOR.MINOR.MICRO`

  Require this version or later of flatpak to install/update to this build.

`--share=SUBSYSTEM`

  Share a subsystem with the host session. This updates the [Context] group in the metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

`--unshare=SUBSYSTEM`

  Don't share a subsystem with the host session. This updates the [Context] group in the metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

`--socket=SOCKET`

  Expose a well-known socket to the application. This updates the [Context] group in the metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times.

  The fallback-x11 option makes the X11 socket available only if there is no Wayland socket. This option was introduced in 0.11.3. To support older Flatpak releases, specify both x11 and fallback-x11. The fallback-x11 option takes precedence when both are supported.

`--nosocket=SOCKET`

  Don't expose a well known socket to the application. This updates the [Context] group in the metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times.

`--device=DEVICE`

  Expose a device to the application. This updates the [Context] group in the metadata. DEVICE must be one of: dri, input, usb, kvm, shm, all. This option can be used multiple times.

`--nodevice=DEVICE`

  Don't expose a device to the application. This updates the [Context] group in the metadata. DEVICE must be one of: dri, input, usb, kvm, shm, all. This option can be used multiple times.

`--allow=FEATURE`

  Allow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

  The `devel` feature allows the application to access certain syscalls such as `ptrace()`, and `perf_event_open()`.

  The `multiarch` feature allows the application to execute programs compiled for an ABI other than the one supported natively by the system. For example, for the `x86_64` architecture, 32-bit `x86` binaries will be allowed as well.

  The `bluetooth` feature allows the application to use bluetooth (AF_BLUETOOTH) sockets. Note, for bluetooth to fully work you must also have network access.

  The `canbus` feature allows the application to use canbus (AF_CAN) sockets. Note, for this work you must also have network access.

  The `per-app-dev-shm` feature shares a single instance of `/dev/shm` between the application, any unrestricted subsandboxes that it creates, and any other instances of the application that are launched while it is running.

`--disallow=FEATURE`

  Disallow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

`--filesystem=FS`

  Allow the application access to a subset of the filesystem. This updates the [Context] group in the metadata. FS can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata(5) for details of the meanings of these filesystems.

`--nofilesystem=FILESYSTEM`

  Remove access to the specified subset of the filesystem from the application. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, an absolute path, or a homedir-relative path like ~/dir. This option can be used multiple times.

`--add-policy=SUBSYSTEM.KEY=VALUE`

  Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata:

      [Policy subsystem]
      key=v1;v2;

  This option can be used multiple times.

`--remove-policy=SUBSYSTEM.KEY=VALUE`

  Remove generic policy option. This option can be used multiple times.

`--usb=TYPE[:DATA]`

  Makes USB devices matching the query visible to the USB portal by adding the query to the application metadata. This does not have any effect on the devices exposed in /dev. TYPE must be one of: all, cls, dev, vnd.

  `all`

    Match all devices.

  `cls`

    A device class and subclass query. DATA must be in the form of CLASS:SUBCLASS where both CLASS and SUBCLASS must valid 2-digit hexadecimal class id numbers. Alternatively, SUBCLASS may be `*` to match all subclasses.

  `dev`

    A device product id query. DATA must be a valid 4-character hexadecimal product id number, for example `0a1b`. It requires a `vnd` filter in the query.

  `vnd`

    A device vendor id query. DATA must be a valid 4-character hexadecimal vendor id number greater than zero, for example `0fab`.

  It is possible to compose multiple device queries together with the `+` sign, for example `--usb=vnd:0123+dev:4567`. The dev filter requires a vnd . Available since 1.15.11.

`--nousb=TYPE[:DATA]`

  Hides USB devices matching the query from the USB portal by adding the query to the application metadata. Queries hiding devices take precedence over queries making devices visible (see `--usb`). The syntax is exactly equal to `--usb`. This does not have any effect on the devices exposed in /dev. Available since 1.15.11.

`--usb-list-file=FILENAME`

  Adds USB device queries to the application metadata from the file FILE_NAME . The line syntax is exactly equal to `--usb`. Additionally, if it starts with ! then the query is like for `--nousb`. Lines sthat starts with `#` are ignored, like a comment. Comments will not be persisted. Available since 1.15.11.

`--usb-list=LIST`

  Adds USB device queries to the application metadata from LIST . The syntax is exactly equal to `--usb` with queries separated by `;`. Additionally, if the query starts with `!` then the query is like for `--nousb`. Available since 1.15.11.

`--env=VAR=VALUE`

  Set an environment variable in the application. This updates the [Environment] group in the metadata. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--unset-env=VAR`

  Unset an environment variable in the application. This updates the unset-environment entry in the [Context] group of the metadata. This option can be used multiple times.

`--env-fd=`FD``

  Read environment variables from the file descriptor `FD`, and set them as if via `--env`. This can be used to avoid environment variables and their values becoming visible to other users.

  Each environment variable is in the form `VAR`=`VALUE` followed by a zero byte. This is the same format used by `env -0` and `/proc/*/environ`.

`--own-name=NAME`

  Allow the application to own the well known name NAME on the session bus. If NAME ends with .*, it allows the application to own all matching names. This updates the [Session Bus Policy] group in the metadata. This option can be used multiple times.

`--talk-name=NAME`

  Allow the application to talk to the well known name NAME on the session bus. If NAME ends with .*, it allows the application to talk to all matching names. This updates the [Session Bus Policy] group in the metadata. This option can be used multiple times.

`--system-own-name=NAME`

  Allow the application to own the well known name NAME on the system bus. If NAME ends with .*, it allows the application to own all matching names. This updates the [System Bus Policy] group in the metadata. This option can be used multiple times.

`--system-talk-name=NAME`

  Allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This updates the [System Bus Policy] group in the metadata. This option can be used multiple times.

`--persist=FILENAME`

  If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This updates the [Context] group in the metadata. This option can be used multiple times.

`--runtime=RUNTIME`, `--sdk=SDK`

  Change the runtime or sdk used by the app to the specified partial ref. Unspecified parts of the ref are taken from the old values or defaults.

`--metadata=GROUP=KEY[=VALUE]`

  Set a generic key in the metadata file. If value is left out it will be set to "true".

`--extension=NAME=VARIABLE[=VALUE]`

  Add extension point info. See the documentation for flatpak-metadata(5) for the possible values of `VARIABLE` and `VALUE`.

`--remove-extension=NAME`

  Remove extension point info.

`--extension-priority=VALUE`

  Set the priority (library override order) of the extension point. Only useful for extensions. 0 is the default, and higher value means higher priority.

`--extra-data=NAME:SHA256:DOWNLOAD-SIZE:INSTALL-SIZE:URL`

  Adds information about extra data uris to the app. These will be downloaded and verified by the client when the app is installed and placed in the `/app/extra` directory. You can also supply an `/app/bin/apply_extra` script that will be run after the files are downloaded.

`--no-exports`

  Don't look for exports in the build.

`--no-inherit-permissions`

  Don't inherit runtime permissions in the app.

`-v`, `--verbose`

  Print debug information during command processing.

  The globally unique identifier of the remote repository, to allow mirrors to be grouped. This must be set to a globally unique reverse DNS string if the repository is to be made publicly available. If a collection ID is already set on an existing repository, this will update it. If not specified, the existing collection ID will be left unchanged.

`--deploy-collection-id`

  Deploy the collection ID (set using `--collection-id`) in the static remote configuration for all clients. This is irrevocable once published in a repository. Use it to decide when to roll out a collection ID to users of an existing repository. If constructing a new repository which has a collection ID, you should typically always pass this option.

`--deploy-sideload-collection-id`

  This is similar to --deploy-collection-id, but it only applies the deploy to clients newer than flatpak 1.7 which supports the new form of sideloads.

  Read environment variables from the file descriptor `FD`, and set them as if via `--env`. This can be used to avoid environment variables and their values becoming visible to other users.

  Each environment variable is in the form `VAR`=`VALUE` followed by a zero byte. This is the same format used by `env -0` and `/proc/*/environ`.

`--own-name=NAME`

  Allow the application to own the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

This overrides to the Context section from the application metadata. This option can be used multiple times.

`--sdk-dir=DIR`

  Normally if there is a `usr` directory in the build dir, this is used for the runtime files (this can be created by `--writable-sdk` or `--type=runtime` arguments to build-init). If you specify `--sdk-dir`, this directory will be used instead. Use this if you passed `--sdk-dir` to build-init.

`--readonly`

  Mount the normally writable destination directories read-only. This can be useful if you want to run something in the sandbox but guarantee that it doesn't affect the build results. For example tests.

`--metadata=FILE`

  Use the specified filename as metadata in the exported app instead of the default file (called `metadata`). This is useful if you build multiple things from a single build tree (such as both a platform and a sdk).

`--log-session-bus`

  Log session bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

`--log-system-bus`

## Name

flatpak-config — Manage configuration

## Synopsis

`flatpak config` [OPTION...]

`flatpak config` [OPTION...] --set KEY VALUE

`flatpak config` [OPTION...] --unset|--get KEY

## Description

The flatpak config command shows or modifies the configuration of a flatpak installation. The following keys are supported:

`languages`

  The languages that are included when installing Locale extensions. The value is a semicolon-separated list of two-letter language codes, or one of the special values `*` or `*all*`. If this key is unset, flatpak defaults to including the `extra-languages` key and the current locale.

`extra-languages`

  This key is used when languages is not set, and it defines extra locale extensions on top of the system configured languages. The value is a semicolon-separated list of locale identifiers (language, optional locale, optional codeset, optional modifier) as documented by setlocale(3) (for example, `en;en_DK;zh_HK.big5hkscs;uz_UZ.utf8@cyrillic`).

For configuration of individual remotes, see flatpak-remote-modify(1). For configuration of individual applications, see flatpak-override(1).

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--list`

  Print all keys and their values.

`--set`

  Set key KEY to VALUE .

`--unset`

  Unset key KEY .

`--get`

  Print value of KEY .

`-u`, `--user`

  Configure per-user installation.

`--system`

  Configure system-wide installation.

`--installation=NAME`

  Configure the system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Examples

$ flatpak config --set languages "sv;en;fi"

## Name

flatpak-create-usb — Copy apps and/or runtimes onto removable media.

## Synopsis

`flatpak create-usb` [OPTION...] MOUNT-PATH REF...

## Description

Copies the specified apps and/or runtimes REF s onto the removable media mounted at MOUNT-PATH , along with all the dependencies and metadata needed for installing them. This is one way of transferring flatpaks between computers that doesn't require an Internet connection. After using this command, the USB drive can be connected to another computer which already has the relevant remote(s) configured, and Flatpak will install or update from the drive offline (see below). If online, the drive will be used as a cache, meaning some objects will be pulled from it and others from the Internet. For this process to work a collection ID must be configured on the relevant remotes on both the source and destination computers, and on the remote server.

On the destination computer one can install from the USB (or any mounted filesystem) using the `--sideload-repo` option with flatpak install. It's also possible to configure sideload paths using symlinks; see flatpak(1). Flatpak also includes systemd units to automatically sideload from hot-plugged USB drives, but these may or may not be enabled depending on your Linux distribution.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is installed, and if there are multiple matches an error message will list the alternatives.

By default this looks for both installed apps and runtimes with the given REF , but you can limit this by using the `--app` or `--runtime` option.

All REF s must be in the same installation (user, system, or other). Otherwise it's ambiguous which repository metadata refs to put on the USB drive.

By default flatpak create-usb uses `.ostree/repo` as the destination directory under MOUNT-PATH but if you specify another location using `--destination-repo` a symbolic link will be created for you in `.ostree/repos.d`. This ensures that either way the repository will be found by flatpak (and other consumers of libostree) for install/update operations.

Unless overridden with the `--system`, `--user`, or `--installation` options, this command searches both the system-wide installation and the per-user one for REF and errors out if it exists in more than one.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-u`, `--user`

  Copy refs from the per-user installation.

`--system`

  Copy refs from the default system-wide installation.

`--installation=NAME`

  Copy refs from a system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`--app`

  Assume that all REF s are apps if not explicitly specified.

`--runtime`

  Assume that all REF s are runtimes if not explicitly specified.

`--destination-repo`=DEST

  Create the repository in DEST under MOUNT-PATH , rather than the default location.

`--allow-partial`

  Don't print a warning when exporting partially installed commits, for example locale extensions without all languages. These can cause problems when installing them, for example if the language config is different on the installing side.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Name

flatpak-document-export — Export a file to a sandboxed application

## Synopsis

`flatpak document-export` [OPTION...] FILE

## Description

Creates a document id for a local file that can be exposed to sandboxed applications, allowing them access to files that they would not otherwise see. The exported files are exposed in a fuse filesystem at `/run/user/$UID/doc/`.

This command also lets you modify the per-application permissions of the documents, granting or revoking access to the file on a per-application basis.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-u`, `--unique`

  Don't reuse an existing document id for the file. This makes it safe to later remove the document when you're finished with it.

`-t`, `--transient`

  The document will only exist for the length of the session. This is useful for temporary grants.

`-n`, `--noexist`

  Don't require the file to exist already.

`-a`, `--app=APPID`

  Grant read access to the specified application. The `--allow` and `--forbid` options can be used to grant or remove additional privileges. This option can be used multiple times.

`-r`, `--allow-read`

  Grant read access to the applications specified with `--app`. This defaults to TRUE.

`--forbid-read`

  Revoke read access for the applications specified with `--app`.

`-w`, `--allow-write`

  Grant write access to the applications specified with `--app`.

`--forbid-write`

  Revoke write access for the applications specified with `--app`.

`-d`, `--allow-delete`

  Grant the ability to remove the document from the document portal to the applications specified with `--app`.

`--forbid-delete`

  Revoke the ability to remove the document from the document portal from the applications specified with `--app`.

`-g`, `--allow-grant-permission`

  Grant the ability to grant further permissions to the applications specified with `--app`.

`--forbid-grant-permission`

  Revoke the ability to grant further permissions for the applications specified with `--app`.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

## Name

flatpak-install — Install an application or runtime

## Synopsis

`flatpak install` [OPTION...] [REMOTE] REF...

`flatpak install` [OPTION...] [--from|--bundle] LOCATION

## Description

Installs an application or runtime. The primary way to install is to specify a REMOTE name as the source and one ore more REF s to specify the application or runtime to install. If REMOTE is omitted, the configured remotes are searched for the first REF and the user is asked to confirm the resulting choice.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is in the remote, and if there are multiple matches you will be prompted to choose one of them. You will also be prompted with choices if REF doesn't match anything in the remote exactly but is similar to one or more refs in the remote (e.g. "devhelp" is similar to "org.gnome.Devhelp"), but this fuzzy matching behavior is disabled if REF contains any slashes or periods.

By default this looks for both apps and runtimes with the given REF in the specified REMOTE , but you can limit this by using the `--app` or `--runtime` option, or by supplying the initial element in the REF .

If REMOTE is a uri or a path (absolute or relative starting with ./) to a local repository, then that repository will be used as the source, and a temporary remote will be created for the lifetime of the REF .

If the specified REMOTE has a collection ID configured on it, Flatpak will search the `sideload-repos` directories configured either with the `--sideload-repo` option, or on a per-installation or system-wide basis (see flatpak(1)).

The alternative form of the command (with `--from` or `--bundle`) allows to install directly from a source such as a `.flatpak` single-file bundle or a `.flatpakref` application description. The options are optional if the first argument has the expected filename extension.

Note that flatpak allows to have multiple branches of an application and runtimes installed and used at the same time. However, only one version of an application can be current, meaning its exported files (for instance desktop files and icons) are visible to the host. The last installed version is made current by default, but this can manually changed with flatpak make-current.

Unless overridden with the `--user` or the `--installation` option, this command installs the application or runtime in the default system-wide installation.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--bundle`

  Treat LOCATION as a single-bundle file. This is assumed if the argument ends with `.flatpak`.

`--from`

  Treat LOCATION as an application description file. This is assumed if the argument ends with `.flatpakref`.

`--reinstall`

  Uninstall first if already installed.

`-u`, `--user`

  Install the application or runtime in a per-user installation.

`--system`

  Install the application or runtime in the default system-wide installation.

`--installation=NAME`

  Install the application or runtime in a system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`--arch=ARCH`

  The default architecture to install for, if not given explicitly in the REF . See flatpak --supported-arches for architectures supported by the host.

`--subpath=PATH`

  Install only a subpath of REF . This is mainly used to install a subset of locales. This can be added multiple times to install multiple subpaths.

`--gpg-file=FILE`

  Check bundle signatures with GPG key from FILE (- for stdin).

`--no-deploy`

  Download the latest version, but don't deploy it.

`--no-pull`

  Don't download the latest version, deploy whatever is locally available.

`--no-related`

  Don't download related extensions, such as the locale data.

`--no-deps`

  Don't verify runtime dependencies when installing.

`--or-update`

  Normally install just ignores things that are already installed (printing a warning), but if --or-update is specified it silently turns it into an update operation instead.

`--app`

  Assume that all REF s are apps if not explicitly specified.

`--runtime`

  Assume that all REF s are runtimes if not explicitly specified.

`--sideload-repo=PATH`

  Adds an extra local ostree repo as a source for installation. This is equivalent to using the `sideload-repos` directories (see flatpak(1)), but can be done on a per-command basis. Any path added here is used in addition to ones in those directories.

`--include-sdk`

  For each app being installed, also installs the SDK that was used to build it. Implies `--or-update`; incompatible with `--no-deps`.

`--include-debug`

  For each ref being installed, as well as all dependencies, also installs its debug info. Implies `--or-update`; incompatible with `--no-deps`.

`-y`, `--assumeyes`

  Automatically answer yes to all questions (or pick the most prioritized answer). This is useful for automation.

`--noninteractive`

  Produce minimal output and avoid most questions. This is suitable for use in non-interactive situations, e.g. in a build script.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Examples

$ flatpak install gedit

$ flatpak install flathub org.gnome.gedit

$ flatpak --installation=default install flathub org.gnome.gedit

$ flatpak --user install flathub org.gnome.gedit//3.30

## Name

flatpak-override — Override application requirements

## Synopsis

`flatpak override` [OPTION...] [APP]

## Description

Overrides the application specified runtime requirements. This can be used to grant a sandboxed application more or less resources than it requested.

By default the application gets access to the resources it requested when it is started. But the user can override it on a particular instance by specifying extra arguments to flatpak run, or every time by using flatpak override.

The application overrides are saved in text files residing in $XDG_DATA_HOME/flatpak/overrides in user mode.

If the application ID APP is not specified then the overrides affect all applications, but the per-application overrides can override the global overrides.

Unless overridden with the `--user` or `--installation` options, this command changes the default system-wide installation.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-u`, `--user`

  Update a per-user installation.

`--system`

  Update the default system-wide installation.

`--installation=NAME`

  Updates a system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`--share=SUBSYSTEM`

  Share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

`--unshare=SUBSYSTEM`

  Don't share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

`--socket=SOCKET`

  Expose a well-known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times.

`--nosocket=SOCKET`

  Don't expose a well-known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times.

`--device=DEVICE`

  Expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, usb, kvm, shm, all. This option can be used multiple times.

`--nodevice=DEVICE`

  Don't expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, usb, kvm, shm, all. This option can be used multiple times.

`--allow=FEATURE`

  Allow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

  See flatpak-build-finish(1) for the meaning of the various features.

`--disallow=FEATURE`

  Disallow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

`--filesystem=FILESYSTEM`

  Allow the application access to a subset of the filesystem. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata(5) for details of the meanings of these filesystems.

`--nofilesystem=FILESYSTEM`

  Undo the effect of a previous `--filesystem=` FILESYSTEM in the app's manifest or a lower-precedence layer of overrides, and/or remove a previous `--filesystem=` FILESYSTEM from this layer of overrides. This overrides the Context section of the application metadata. FILESYSTEM can take the same values as for `--filesystem`, but the :ro and :create suffixes are not used here. This option can be used multiple times.

  This option does not prevent access to a more narrowly-scoped `--filesystem`. For example, if an application has the equivalent of `--filesystem=xdg-config/MyApp` in its manifest or as a system-wide override, and `flatpak override --user --nofilesystem=home` as a per-user override, then it will be prevented from accessing most of the home directory, but it will still be allowed to access `$XDG_CONFIG_HOME/MyApp`.

  As a special case, `--nofilesystem=host:reset` will ignore all `--filesystem` permissions inherited from the app manifest or a lower-precedence layer of overrides, in addition to having the behaviour of `--nofilesystem=host`.

`--add-policy=SUBSYSTEM.KEY=VALUE`

  Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata:

      [Policy subsystem]
      key=v1;v2;

  This option can be used multiple times.

`--remove-policy=SUBSYSTEM.KEY=VALUE`

  Remove generic policy option. This option can be used multiple times.

`--env=VAR=VALUE`

  Set an environment variable in the application. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--unset-env=VAR`

  Unset an environment variable in the application. This overrides the unset-environment entry in the [Context] group of the metadata, and the [Environment] group. This option can be used multiple times.

`--env-fd=`FD``

  Read environment variables from the file descriptor `FD`, and set them as if via `--env`. This can be used to avoid environment variables and their values becoming visible to other users.

  Each environment variable is in the form `VAR`=`VALUE` followed by a zero byte. This is the same format used by `env -0` and `/proc/*/environ`.

`--own-name=NAME`

  Allow the application to own the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--talk-name=NAME`

  Allow the application to talk to the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--no-talk-name=NAME`

  Don't allow the application to talk to the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--system-own-name=NAME`

  Allow the application to own the well known name NAME on the system bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--system-talk-name=NAME`

  Allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--system-no-talk-name=NAME`

  Don't allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--persist=FILENAME`

  If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--reset`

  Remove overrides. If an APP is given, remove the overrides for that application, otherwise remove the global overrides.

`--show`

  Shows overrides. If an APP is given, shows the overrides for that application, otherwise shows the global overrides.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Name

flatpak-remote-add — Add a remote repository

## Synopsis

`flatpak remote-add` [OPTION...] NAME LOCATION

## Description

Adds a remote repository to the flatpak repository configuration. NAME is the name for the new remote, and LOCATION is a url or pathname. The LOCATION is either a flatpak repository, or a `.flatpakrepo` file which describes a repository. In the former case you may also have to specify extra options, such as the gpg key for the repo.

Unless overridden with the `--user` or `--installation` options, this command changes the default system-wide installation.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--from`

  Assume the URI is a .flatpakrepo file rather than the repository itself. This is enabled by default if the extension is .flatpakrepo, so generally you don't need this option.

`-u`, `--user`

  Modify the per-user configuration.

`--system`

  Modify the default system-wide configuration.

`--installation=NAME`

  Modify a system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`--no-gpg-verify`

  Disable GPG verification for the added remote.

`--prio=PRIO`

  Set the priority for the remote. Default is 1, higher is more prioritized. This is mainly used for graphical installation tools. It is also used when searching for a remote to provide an app's runtime. The app's origin is checked before other remotes with the same priority.

`--subset=SUBSET`

  Limit the refs available from the remote to those that are part of the named subset.

`--no-enumerate`

  Mark the remote as not enumerated. This means the remote will not be used to list applications, for instance in graphical installation tools.

`--no-use-for-deps`

  Mark the remote as not to be used for automatic runtime dependency resolution.

`--if-not-exists`

  Do nothing if the provided remote already exists.

`--disable`

  Disable the added remote.

`--title=TITLE`

  A title for the remote, e.g. for display in a UI.

`--comment=COMMENT`

  A single-line comment for the remote, e.g. for display in a UI.

`--description=DESCRIPTION`

  A full-paragraph description for the remote, e.g. for display in a UI.

`--homepage=URL`

  URL for a website for the remote, e.g. for display in a UI.

`--icon=URL`

  URL for an icon for the remote, e.g. for display in a UI.

`--default-branch=BRANCH`

  A default branch for the remote, mainly for use in a UI.

`--filter=PATH`

  Add a local filter to the remote. A filter file is a list of lines, each file starting with "allow" or "deny", and then a glob for the ref to allow or disallow. The globs specify a partial ref (i.e. you can leave out trailing parts which will then match everything), but otherwise only "*" is special, matching anything in that part of the ref.

  By default all refs are allowed, but if a ref matches a deny rule it is disallowed unless it specifically matches an allow rule. This means you can use this to implement both allowlisting and blocklisting.

  Here is an example filter file:

      # This is an allowlist style filter as it denies all first
      deny *
      allow runtime/org.freedesktop.*
      allow org.some.app/arm
      allow org.signal.Signal/*/stable
      allow org.signal.Signal.*/*/stable

`--gpg-import=FILE`

  Import gpg keys from the specified keyring file as trusted for the new remote. If the file is - the keyring is read from standard input.

`--authenticator-name=NAME`

  Specify the authenticator to use for the remote.

`--authenticator-option=KEY=VALUE`

  Specify an authenticator option for the remote.

`--authenticator-install`

  Enable auto-installation of authenticator.

`--no-authenticator-install`

  Disable auto-installation of authenticator.

`--no-follow-redirect`

  Do not follow xa.redirect-url defined in the summary file.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

flatpak-repair — Repair a flatpak installation

## Synopsis

`flatpak repair` [OPTION...]

## Description

Repair a flatpak installation by pruning and reinstalling invalid objects. The repair command does all of the following:

- Scan all locally available refs, removing any that don't correspond to a deployed ref.

- Verify each commit they point to, removing any invalid objects and noting any missing objects.

- Remove any refs that had an invalid object, and any non-partial refs that had missing objects.

- Prune all objects not referenced by a ref, which gets rid of any possibly invalid non-scanned objects.

- Enumerate all deployed refs and re-install any that are not in the repo (or are partial for a non-subdir deploy).

Note that flatpak repair has to be run with root privileges to operate on the system installation.

An alternative command for repairing OSTree repositories is ostree fsck.

## Options

## Name

flatpak-run — Run an application or open a shell in a runtime

## Synopsis

`flatpak run` [OPTION...] REF [ARG...]

## Description

If REF names an installed application, Flatpak runs the application in a sandboxed environment. Extra arguments are passed on to the application. The current branch and arch of the application is used unless otherwise specified with `--branch` or `--arch`. See flatpak-make-current(1).

If REF names a runtime, a shell is opened in the runtime. This is useful for development and testing. If there is ambiguity about which branch to use, you will be prompted to choose. Use `--branch` to avoid this. The primary arch is used unless otherwise specified with `--arch`.

By default, Flatpak will look for the application or runtime in the per-user installation first, then in all system installations. This can be overridden with the `--user`, `--system` and `--installation` options.

Flatpak creates a sandboxed environment for the application to run in by mounting the right runtime at `/usr` and a writable directory at `/var`, whose content is preserved between application runs. The application itself is mounted at `/app`.

The details of the sandboxed environment are controlled by the application metadata and various options like `--share` and `--socket` that are passed to the run command: Access is allowed if it was requested either in the application metadata file or with an option and the user hasn't overridden it.

The remaining arguments are passed to the command that gets run in the sandboxed environment. See the `--file-forwarding` option for handling of file arguments.

Environment variables are generally passed on to the sandboxed application, with certain exceptions. The application metadata can override environment variables, as well as the `--env` option. Apart from that, Flatpak always unsets or overrides the following variables, since their session values are likely to interfere with the functioning of the sandbox:

PATH
LD_LIBRARY_PATH
LD_PRELOAD
LD_AUDIT
XDG_CONFIG_DIRS
XDG_DATA_DIRS
SHELL
TEMP
TEMPDIR

__EGL_VENDOR_LIBRARY_DIRS
__EGL_VENDOR_LIBRARY_FILENAMES

Also several environment variables with the prefix "GST_" that are used by gstreamer are unset (since Flatpak 1.12.5).

Flatpak also overrides the XDG environment variables to point sandboxed applications at their writable filesystem locations below `~/.var/app/$APPID/`:

XDG_DATA_HOME
XDG_CONFIG_HOME
XDG_CACHE_HOME
XDG_STATE_HOME (since Flatpak 1.13)

Apps can use the `--persist=.local/state` and `--unset-env=XDG_STATE_HOME` options to get a Flatpak 1.13-compatible `~/.local/state` on older versions of Flatpak.

The host values of these variables are made available inside the sandbox via these HOST_-prefixed variables:

HOST_XDG_DATA_HOME
HOST_XDG_CONFIG_HOME
HOST_XDG_CACHE_HOME
HOST_XDG_STATE_HOME (since Flatpak 1.13)

Flatpak sets the environment variable `FLATPAK_ID` to the application ID of the running app.

Flatpak also bind-mounts as read-only the host's `/etc/os-release` (if available, or `/usr/lib/os-release` as a fallback) to `/run/host/os-release` in accordance with the os-release specification.

If parental controls support is enabled, flatpak will check the current user’s parental controls settings, and will refuse to run an app if it is blocklisted for the current user.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-u`, `--user`

  Look for the application and runtime in per-user installations.

`--system`

  Look for the application and runtime in the default system-wide installations.

`--installation=NAME`

  Look for the application and runtime in the system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

`--arch=ARCH`

  The architecture to run. See flatpak --supported-arches for architectures supported by the host.

`--command=COMMAND`

  The command to run instead of the one listed in the application metadata.

`--cwd=DIR`

  The directory to run the command in. Note that this must be a directory inside the sandbox.

`--branch=BRANCH`

  The branch to use.

`-d`, `--devel`

  Use the devel runtime that is specified in the application metadata instead of the regular runtime, and use a seccomp profile that is less likely to break development tools.

`--runtime=RUNTIME`

  Use this runtime instead of the one that is specified in the application metadata. This is a full tuple, like for example org.freedesktop.Sdk/x86_64/1.2 , but partial tuples are allowed. Any empty or missing parts are filled in with the corresponding values specified by the app.

`--runtime-version=VERSION`

  Use this version of the runtime instead of the one that is specified in the application metadata. This overrides any version specified with the --runtime option.

`--share=SUBSYSTEM`

  Share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

`--unshare=SUBSYSTEM`

  Don't share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

`--socket=SOCKET`

  Expose a well known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times.

`--nosocket=SOCKET`

  Don't expose a well known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be used multiple times.

`--device=DEVICE`

  Expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, usb, input, kvm, shm, all. This option can be used multiple times.

`--nodevice=DEVICE`

  Don't expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, usb, input, kvm, shm, all. This option can be used multiple times.

`--allow=FEATURE`

  Allow access to a specific feature. This overrides to the Context section from the application metadata. FEATURE must be one of: devel, multiarch, bluetooth. This option can be used multiple times.

  See flatpak-build-finish(1) for the meaning of the various features.

`--disallow=FEATURE`

  Disallow access to a specific feature. This overrides to the Context section from the application metadata. FEATURE must be one of: devel, multiarch, bluetooth. This option can be used multiple times.

`--filesystem=FILESYSTEM`

  Allow the application access to a subset of the filesystem. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata(5) for details of the meanings of these filesystems.

`--nofilesystem=FILESYSTEM`

  Undo the effect of a previous `--filesystem=` FILESYSTEM in the app's manifest and/or the overrides set up with flatpak-override(1). This overrides the Context section of the application metadata. FILESYSTEM can take the same values as for `--filesystem`, but the :ro and :create suffixes are not used here. This option can be used multiple times.

  This option does not prevent access to a more narrowly-scoped `--filesystem`. For example, if an application has the equivalent of `--filesystem=xdg-config/MyApp` in its manifest or as a system-wide override, and `flatpak override --user --nofilesystem=home` as a per-user override, then it will be prevented from accessing most of the home directory, but it will still be allowed to access `$XDG_CONFIG_HOME/MyApp`.

  As a special case, `--nofilesystem=host:reset` will ignore all `--filesystem` permissions inherited from the app manifest or flatpak-override(1), in addition to having the behaviour of `--nofilesystem=host`.

`--add-policy=SUBSYSTEM.KEY=VALUE`

  Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata:

      [Policy subsystem]
      key=v1;v2;

  This option can be used multiple times.

`--remove-policy=SUBSYSTEM.KEY=VALUE`

  Remove generic policy option. This option can be used multiple times.

`--usb=TYPE[:DATA]`

  Adds a USB device query to the application metadata. This allows device enumeration and usage by the USB portal. TYPE must be one of: all, cls, dev, vnd.

  `all`

    Match all devices.

  `cls`

    A device class and subclass query. DATA must be in the form of CLASS:SUBCLASS where both CLASS and SUBCLASS must be a valid 2-digit hexadecimal class id number. Alternatively, SUBCLASS may be `*` to match all subclasses.

  `dev`

    A device product id query. DATA must be a valid 4-digit hexadecimal product id number, for example `0a1b`. It requires a `vnd` filter in the query.

  `vnd`

    A device vendor id query. DATA must be a valid 4-digit hexadecimal vendor id number greater than zero, for example `0fab`.

  It is possible to compose multiple device queries together with the `+` sign, for example `--usb=vnd:0123+dev:4567`. The dev filter requires a vnd . Available since 1.15.11.

`--nousb=VENDOR_ID:PRODUCT_ID`

  Adds a blocking USB device query to the application metadata. Blocked devices take precedence over allowed devices. The syntax is exactly equal to `--usb`. Available since 1.15.11.

`--env=VAR=VALUE`

  Set an environment variable in the application. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--unset-env=VAR`

  Unset an environment variable in the application. This overrides the unset-environment entry in the [Context] group of the metadata, and the [Environment] group. This option can be used multiple times.

`--env-fd=`FD``

  Read environment variables from the file descriptor `FD`, and set them as if via `--env`. This can be used to avoid environment variables and their values becoming visible to other users.

  Each environment variable is in the form `VAR`=`VALUE` followed by a zero byte. This is the same format used by `env -0` and `/proc/*/environ`.

`--own-name=NAME`

  Allow the application to own the well known name NAME on the session bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--talk-name=NAME`

  Allow the application to talk to the well known name NAME on the session bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--no-talk-name=NAME`

  Don't allow the application to talk to the well known name NAME on the session bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--system-own-name=NAME`

  Allow the application to own the well known name NAME on the system bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--system-talk-name=NAME`

  Allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--system-no-talk-name=NAME`

  Don't allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--a11y-own-name=NAME`

  Allow the application to own the well known name NAME on the a11y bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--persist=FILENAME`

  If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This overrides to the Context section from the application metadata. This option can be used multiple times.

`--no-session-bus`

  Run this instance without the filtered access to the session dbus connection. Note, this is the default when run with --sandbox.

`--session-bus`

  Allow filtered access to the session dbus connection. This is the default, except when run with --sandbox.

  In sandbox mode, even if you allow access to the session bus the sandbox cannot talk to or own the application ids (org.the.App.*) on the bus (unless explicitly added), only names in the .Sandboxed subset (org.the.App.Sandboxed.* and org.mpris.MediaPlayer2.org.the.App.Sandboxed.*).

`--no-a11y-bus`

  Run this instance without the access to the accessibility bus. Note, this is the default when run with --sandbox.

`--a11y-bus`

  Allow access to the accessibility bus. This is the default, except when run with --sandbox.

`--sandbox`

  Run the application in sandboxed mode, which means dropping all the extra permissions it would otherwise have, as well as access to the session/system/a11y busses and document portal.

`--log-session-bus`

  Log session bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

`--log-system-bus`

  Log system bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

`-p`, `--die-with-parent`

  Kill the entire sandbox when the launching process dies.

`--parent-pid=PID`

  Specifies the pid of the "parent" flatpak, used by --parent-expose-pids and --parent-share-pids.

`--parent-expose-pids`

  Make the processes of the new sandbox visible in the sandbox of the parent flatpak, as defined by --parent-pid.

`--parent-share-pids`

  Use the same process ID namespace for the processes of the new sandbox and the sandbox of the parent flatpak, as defined by --parent-pid. Implies --parent-expose-pids.

`--instance-id-fd`

  Write the instance ID string to the given file descriptor.

`--file-forwarding`

  If this option is specified, the remaining arguments are scanned, and all arguments that are enclosed between a pair of '@@' arguments are interpreted as file paths, exported in the document store, and passed to the command in the form of the resulting document path. Arguments between "@@u" and "@@" are considered URIs, and any "file:" URIs are exported. The exports are non-persistent and with read and write permissions for the application.

`--app-path=`PATH``

  Instead of mounting the app's content on `/app` in the sandbox, mount `PATH` on `/app`, and the app's content on `/run/parent/app`. If the app has extensions, they will also be redirected into `/run/parent/app`, and will not be included in the `LD_LIBRARY_PATH` inside the sandbox.

`--app-path=`

  As a special case, `--app-path=` (with an empty `PATH`) results in an empty directory being mounted on `/app`.

`--usr-path=`PATH``

  Instead of mounting the runtime's files on `/usr` in the sandbox, mount `PATH` on `/usr`, and the runtime's normal files on `/run/parent/usr`. If the runtime has extensions, they will also be redirected into `/run/parent/usr`, and will not be included in the `LD_LIBRARY_PATH` inside the sandbox.

  This option will usually only be useful if it is combined with `--app-path=` and `--env=LD_LIBRARY_PATH=`...``.

## Examples

$ flatpak run org.gnome.gedit

$ flatpak run --devel --command=bash org.gnome.Builder

$ flatpak run --command=bash org.gnome.Sdk

$ flatpak run org.gnome.Boxes --nousb=0fd9:*

flatpak-uninstall — Uninstall an application or runtime

## Synopsis

`flatpak uninstall` [OPTION...] [REF...]

## Description

Uninstalls an application or runtime. REF is a reference to the application or runtime to uninstall.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is installed, and if there are multiple matches you will be prompted to choose between them. You will also be prompted if REF doesn't match any installed ref exactly but is similar (e.g. "gedit" is similar to "org.gnome.gedit"), but this fuzzy matching behavior is disabled if REF contains any slashes or periods.

By default this looks for both installed apps and runtimes with the given REF , but you can limit this by using the `--app` or `--runtime` option, or by supplying the initial element in the REF .

Normally, this command removes the ref for this application/runtime from the local OSTree repository and purges any objects that are no longer needed to free up disk space. If the same application is later reinstalled, the objects will be pulled from the remote repository again. The `--keep-ref` option can be used to prevent this.

When `--delete-data` is specified while removing an app, its data directory in `~/.var/app` and any permissions it might have are removed. When `--delete-data` is used without a REF , all 'unowned' app data is removed.

Unless overridden with the `--system`, `--user`, or `--installation` options, this command searches both the system-wide installation and the per-user one for REF and errors out if it exists in more than one.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`--keep-ref`

  Keep the ref for the application and the objects belonging to it in the local repository.

`-u`, `--user`

  Uninstalls from a per-user installation.

`--system`

  Uninstalls from the default system-wide installation.

`--installation=NAME`

  Uninstalls from a system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`--arch=ARCH`

  The architecture to uninstall, instead of the architecture of the host system. See flatpak --supported-arches for architectures supported by the host.

`--all`

  Remove all refs on the system.

`--unused`

  Remove unused refs on the system.

`-y`, `--assumeyes`

  Automatically answer yes to all questions. This is useful for automation.

`--noninteractive`

  Produce minimal output and avoid most questions. This is suitable for use in non-interactive situations, e.g. in a build script.

`--app`

  Only look for an app with the given name.

`--runtime`

  Only look for a runtime with the given name.

`--no-related`

  Don't uninstall related extensions, such as the locale data.

`--force-remove`

  Remove files even if they're in use by a running application.

`--delete-data`

  Remove app data in `~/.var/app` and in the permission store.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Examples

$ flatpak --user uninstall org.gnome.gedit

## Name

flatpak-update — Update an application or runtime

## Synopsis

`flatpak update` [OPTION...] [REF...]

`flatpak update` [OPTION...] --appstream [REMOTE]

## Description

Updates applications and runtimes. REF is a reference to the application or runtime to update. If no REF is given, everything is updated, as well as appstream info for all remotes.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is installed, and if there are multiple matches an error message will list the alternatives.

By default this looks for both apps and runtimes with the given REF , but you can limit this by using the `--app` or `--runtime` option, or by supplying the initial element in the REF .

Normally, this command updates the application to the tip of its branch. But it is possible to check out another commit, with the `--commit` option.

If the configured remote for a ref being updated has a collection ID configured on it, Flatpak will search the `sideload-repos` directories configured either with the `--sideload-repo` option, or on a per-installation or system-wide basis (see flatpak(1)).

Note that updating a runtime is different from installing a different branch, and runtime updates are expected to keep strict compatibility. If an application update does cause a problem, it is possible to go back to the previous version, with the `--commit` option.

In addition to updates, this command will offer to uninstall any unused end-of-life runtimes. Runtimes that were explicitly installed (not as a dependency) or explicitly pinned (see flatpak-pin(1)) are left installed even if unused and end-of-life.

Unless overridden with the `--user`, `--system` or `--installation` option, this command updates any matching refs in the standard system-wide installation and the per-user one.

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-u`, `--user`

  Update a per-user installation.

`--system`

  Update the default system-wide installation.

`--installation=NAME`

  Updates a system-wide installation specified by NAME among those defined in `/etc/flatpak/installations.d/`. Using `--installation=default` is equivalent to using `--system`.

`--arch=ARCH`

  The architecture to update for. See flatpak --supported-arches for architectures supported by the host.

`--subpath=PATH`

  Install only a subpath of the ref. This is mainly used to install a subset of locales. This can be added multiple times to install multiple subpaths. If this is not specified the subpaths specified at install time are reused.

`--commit=COMMIT`

  Update to this commit, instead of the tip of the branch. You can find commits using flatpak remote-info --log REMOTE REF.

`--no-deploy`

  Download the latest version, but don't deploy it.

`--no-pull`

  Don't download the latest version, deploy whatever is locally available.

`--no-related`

  Don't download related extensions, such as the locale data.

`--no-deps`

  Don't update or install runtime dependencies when installing.

`--app`

  Only look for an app with the given name.

`--appstream`

  Update appstream for REMOTE , or all remotes if no remote is specified.

`--runtime`

  Only look for a runtime with the given name.

`--sideload-repo=PATH`

  Adds an extra local ostree repo as a source for installation. This is equivalent to using the `sideload-repos` directories (see flatpak(1)), but can be done on a per-command basis. Any path added here is used in addition to ones in those directories.

`-y`, `--assumeyes`

  Automatically answer yes to all questions (or pick the most prioritized answer). This is useful for automation.

`--noninteractive`

  Produce minimal output and avoid most questions. This is suitable for use in non-interactive situations, e.g. in a build script.

`--force-remove`

  Remove old files even if they're in use by a running application.

`-v`, `--verbose`

  Print debug information during command processing.

`--ostree-verbose`

  Print OSTree debug information during command processing.

## Name

flatpak-spawn — Run commands in a sandbox

## Synopsis

`flatpak-spawn` [OPTION...] COMMAND [ARGUMENT...]

## Description

Unlike other flatpak commands, flatpak-spawn is available to applications inside the sandbox. It runs COMMAND outside the sandbox: either in another sandbox, or on the host.

When called without `--host`, flatpak-spawn uses the Flatpak portal to create a copy of the sandbox it was called from, optionally using tighter permissions and optionally the latest version of the app and runtime (see `--latest-version`).

## Options

The following options are understood:

`-h`, `--help`

  Show help options and exit.

`-v`, `--verbose`

  Print debug information

`--forward-fd=FD`

  Forward a file descriptor

`--clear-env`

  Run with a clean environment

`--watch-bus`

  Make the spawned command exit when flatpak-spawn itself exits; notably, this occurs when its connection to the session bus is closed.

`--env=VAR=VALUE`

  Set an environment variable

`--latest-version`

  Use the latest version of the refs that are used to set up the sandbox

`--no-network`

  Run without network access

`--sandbox`

  Run fully sandboxed. See the documentation for the `--sandbox` option in flatpak-run(1)

  See the `--sandbox-expose` and `--sandbox-expose-ro` options for selective file access.

`--sandbox-expose=NAME`

  Expose read-write access to a file in the sandbox.

  Note that absolute paths or subdirectories are not allowed. The files must be in the `sandbox` subdirectory of the instance directory (i.e. `~/.var/app/$APP_ID/sandbox`).

  This option is useful in combination with `--sandbox` (otherwise the instance directory is accessible anyway).

`--sandbox-expose-ro=NAME`

  Expose readonly access to a file in the sandbox.

  Note that absolute paths or subdirectories are not allowed. The files must be in the `sandbox` subdirectory of the instance directory (i.e. `~/.var/app/$APP_ID/sandbox`).

  This option is useful in combination with `--sandbox` (otherwise the instance directory is accessible anyway).

`--host`

  Run the command unsandboxed on the host. This requires access to the org.freedesktop.Flatpak D-Bus interface.

`--directory=DIR`

  The working directory in which to run the command.

  Note that the given directory must exist in the sandbox or, when used in conjunction with `--host`, on the host.

## File Formats

## Name

flatpakrepo — Reference to a remote

## Description

Flatpak uses flatpakrepo files to share information about remotes. The `flatpakrepo` file contains enough information to add the remote. Use the flatpak remote-add --from command to do so.

flatpakrepo files may also contain additional information that is useful when displaying a remote to the user, e.g. in an app store.

The filename extension commonly used for flatpakrepo files is `.flatpakrepo`.

flatpakrepo files can also be placed in `/usr/share/flatpak/remotes.d/` and `/etc/flatpak/remotes.d/` to statically preconfigure system-wide remotes. Such files must use the `.flatpakrepo` extension. If a file with the same name exists in both, the file under `/etc` will take precedence.

## File format

The flatpakrepo file is using the same .ini file format that is used for systemd unit files or application .desktop files.

### [Flatpak Repo]

All the information is contained in the [Flatpak Repo] group.

The following keys can be present in this group:

`Version` (uint64)

  The version of the file format, must be 1 if present.

`Url` (string)

  The url for the remote. This key is mandatory.

`GPGKey` (string)

  The base64-encoded gpg key for the remote.

`DefaultBranch` (string)

  The default branch to use for this remote.

`Subset` (string)

  Limit the remote to the named subset of refs.

`Title` (string)

  The title of the remote. This should be a user-friendly name that can be displayed e.g. in an app store.

`Comment` (string)

  A short summary of the remote, for display e.g. in an app store.

`Description` (string)

  A longer description of the remote, for display e.g. in an app store.

`Icon` (string)

  The url for an icon that can be used to represent the remote.

`Homepage` (string)

  The url of a webpage describing the remote.

`Filter` (string)

  The path of a local file to use to filter remote refs. See flatpak-remote-add(1) for details on the format of the file.

  Note: This field is treated a bit special by flatpak remote-add. If you install a remote with --if-not-exists then and the remote is already configured, then the filter field of the remote configuration will be update anyway. And, if the filter field is *not* specified then any existing filters are cleared. The goal here is to allow a pre-configured filtered remote to be replaced with the regular one if you add the normal upstream (unfiltered) flatpakrepo file.

`DeploySideloadCollectionID` (string)

  The collection ID of the remote, if it has one. This uniquely identifies the collection of apps in the remote, to allow peer to peer redistribution (see flatpak(1)). It is recommended to use this key over DeployCollectionID or CollectionID because only newer clients (Flatpak 1.12.8 or later) pay attention to it (and older clients don't handle collection IDs properly).

`DeployCollectionID` (string)

  This is deprecated but still supported for backwards compatibility. Use DeploySideloadCollectionID instead.

`CollectionID` (string)

  This is deprecated but still supported for backwards compatibility. Use DeploySideloadCollectionID instead.

## Example

    [Flatpak Repo]
    Title=gedit
    Url=http://sdk.gnome.org/repo-apps/

    DeployCollectionID=org.gnome.Apps

## Name

flatpakref — Reference to a remote for an application or runtime

## Description

Flatpak uses flatpakref files to share information about a remote for a single application. The `flatpakref` file contains enough information to add the remote and install the application. Use the flatpak install --from command to do so.

flatpakref files may also contain additional information that is useful when displaying the application to the user, e.g. in an app store.

The filename extension commonly used for flatpakref files is `.flatpakref`.

A flatpakref file can also refer to a remote for a runtime.

## File format

The flatpakref file is using the same .ini file format that is used for systemd unit files or application .desktop files.

### [Flatpak Ref]

All the information is contained in the [Flatpak Ref] group.

The following keys can be present in this group:

`Version` (uint64)

  The version of the file format, must be 1 if present.

`Name` (string)

  The fully qualified name of the runtime or application. This key is mandatory.

`Url` (string)

  The url for the remote. This key is mandatory.

`Branch` (string)

  The name of the branch from which to install the application or runtime. If this key is not specified, the "master" branch is used.

`Title` (string)

  The title of the application or runtime. This should be a user-friendly name that can be displayed e.g. in an app store.

`Comment` (string)

  A short summary of the application or runtime, for display e.g. in an app store.

`Description` (string)

  A longer description of the application or runtime, for display e.g. in an app store.

`Icon` (string)

  The url for an icon that can be used to represent the application or runtime.

`Homepage` (string)

  The url of a webpage describing the application or runtime.

`DeploySideloadCollectionID` (string)

  The collection ID of the remote, if it has one. This uniquely identifies the collection of apps in the remote, to allow peer to peer redistribution (see flatpak(1)). It is recommended to use this key over DeployCollectionID or CollectionID because only newer clients (Flatpak 1.12.8 or later) pay attention to it (and older clients don't handle collection IDs properly).

`DeployCollectionID` (string)

  This is deprecated but still supported for backwards compatibility. Use DeploySideloadCollectionID instead.

`CollectionID` (string)

  This is deprecated but still supported for backwards compatibility. Use DeploySideloadCollectionID instead.

`IsRuntime` (boolean)

  Whether this file refers to a runtime. If this key is not specified, the file is assumed to refer to an application.

`GPGKey` (string)

  The base64-encoded gpg key for the remote.

`RuntimeRepo` (string)

  The url for a .flatpakrepo file for the remote where the runtime can be found. Note that if the runtime is available in the remote providing the app, that remote may be used instead but the one specified by this option will still be added.

`SuggestRemoteName` (string)

  A suggested name for the remote.

## Example

    [Flatpak Ref]
    Title=gedit
    Name=org.gnome.gedit
    Branch=stable
    Url=http://sdk.gnome.org/repo-apps/
    IsRuntime=false

    DeployCollectionID=org.gnome.Apps

## Name

flatpak-installation — Configuration for an installation location

## Description

flatpak can operate in system-wide or per-user mode. The system-wide data is located in `$prefix/var/lib/flatpak/`, and the per-user data is in `$HOME/.local/share/flatpak/`.

In addition to the default installation locations, more system-wide installations can be defined via configuration files `/etc/flatpak/installations.d/`, which must have the .conf extension and follow the format described below.

## File format

The installation config file format is using the same .ini file format that is used for systemd unit files or application .desktop files.

### [Installation …]

All the configuration for the the installation location with name NAME is contained in the [Installation "NAME"] group.

The following keys are recognized:

`Path` (string)

  The path for this installation. This key is mandatory.

`DisplayName` (string)

  The name to use when showing this installation in the UI.

`Priority` (integer)

  A priority for this installation.

`StorageType` (string)

  The type of storage used for this installation. Possible values include: network, mmc, sdcard, harddisk.

## Examples

    [Installation "extra"]
    Path=/location/of/sdcard
    DisplayName=Extra Installation
    StorageType=sdcard

## Name

flatpak-metadata — Information about an application or runtime

## Description

Flatpak uses metadata files to describe applications and runtimes. The `metadata` file for a deployed application or runtime is placed in the toplevel deploy directory. For example, the metadata for the locally installed application org.gnome.Calculator is in `~/.local/share/flatpak/app/org.gnome.Calculator/current/active/metadata`.

Most aspects of the metadata configuration can be overridden when launching applications, either temporarily via options of the flatpak run command, or permanently with the flatpak override command.

A metadata file describing the effective configuration is available inside the running sandbox at `/.flatpak-info`. For compatibility with older Flatpak versions, `/run/user/$UID/flatpak-info` is a symbolic link to the same file.

## File format

The metadata file is using the same .ini file format that is used for systemd unit files or application .desktop files.

### [Application] or [Runtime]

Metadata for applications starts with an [Application] group, metadata for runtimes with a [Runtime] group.

The following keys can be present in these groups:

`name` (string)

  The name of the application or runtime. This key is mandatory.

`runtime` (string)

  The fully qualified name of the runtime that is used by the application. This key is mandatory for applications.

`sdk` (string)

  The fully qualified name of the sdk that matches the runtime. Available since 0.1.

`command` (string)

  The command to run. Only relevant for applications. Available since 0.1.

`required-flatpak` (string list)

  The required version of Flatpak to run this application or runtime. For applications, this was available since 0.8.0. For runtimes, this was available since 0.9.1, and backported to 0.8.3 for the 0.8.x branch.

  Flatpak after version 1.4.3 and 1.2.5 support multiple versions here. This can be useful if you need to support features that are backported to a previous stable series. For example if you want to use a feature added in 1.6.0 that was also backported to 1.4.4 you would use `1.6.0;1.4.4;`. Note that older versions of flatpak will just use the first element in the list, so make that the largest version.

`tags` (string list)

  Tags to include in AppStream XML. Typical values in use on Flathub include `beta`, `stable`, `proprietary` and `upstream-maintained`. Available since 0.4.12.

### [Context]

This group determines various system resources that may be shared with the application when it is run in a flatpak sandbox.

All keys in this group (and the group itself) are optional.

`shared` (list)

  List of subsystems to share with the host system. Possible subsystems: network, ipc. Available since 0.3.

`sockets` (list)

  List of well-known sockets to make available in the sandbox. Possible sockets: x11, wayland, fallback-x11, pulseaudio, session-bus, system-bus, ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. When making a socket available, flatpak also sets well-known environment variables like DISPLAY or DBUS_SYSTEM_BUS_ADDRESS to let the application find sockets that are not in a fixed location. Available since 0.3.

`devices` (list)

  List of devices to make available in the sandbox. This just expose the devices nodes, it doesn't grant any permission that the user doesn't already have. Possible values:

  `dri`

    Graphics direct rendering (`/dev/dri`). Available since 0.3.

  `input`

    Input devices (`/dev/input`). Available since 1.15.6.

  `usb`

    USB device bus (all device nodes below `/dev/bus/usb`). Available since 1.15.11.

  `kvm`

    Virtualization (`/dev/kvm`). Available since 0.6.12.

  `all`

    All device nodes in `/dev`, but not /dev/shm (which is separately specified). Available since 0.6.6.

  `shm`

    Access to the host /dev/shm (`/dev/shm`). Available since 1.6.1.

`filesystems` (list)

  List of filesystem subsets to make available to the application. Possible values:

  `home`

    The entire home directory. Available since 0.3.

  `home/`path``

    Alias for `~/path` Available since 1.10. For better compatibility with older Flatpak versions, prefer to write this as `~/path`.

  `host`

    The entire host file system, except for directories that are handled specially by Flatpak. In particular, this shares `/home`, `/media`, `/opt`, `/run/media` and `/srv` if they exist.

    `/dev` is not shared: use `devices=all;` instead.

    Parts of `/sys` are always shared. This option does not make additional files in /sys available.

    Additionally, this keyword provides all of the same directories in `/run/host` as the `host-os` and `host-etc` keywords. If this keyword is used in conjunction with one of the `host-` keywords, whichever access level is higher (more permissive) will be used for the directories in `/run/host`: for example, `host:rw;host-os:ro;` is equivalent to `host:rw;`.

    These other reserved directories are currently excluded: `/app`, `/bin`, `/boot`, `/efi`, `/etc`, `/lib`, `/lib32`, `/lib64`, `/proc`, `/root`, `/run`, `/sbin`, `/tmp`, `/usr`, `/var`.

    Available since 0.3.

  `host-os`

    The host operating system's libraries, executables and static data from `/usr` and the related directories `/bin`, `/lib`, `/lib32`, `/lib64`, `/sbin`. Additionally, this keyword provides access to a subset of `/etc` that is associated with packaged libraries and executables, even if the `host-etc` keyword was not used: `/etc/ld.so.cache`, (used by the dynamic linker) and `/etc/alternatives` (on operating systems that use it, such as Debian).

    To avoid conflicting with the Flatpak runtime, these are mounted in the sandbox at `/run/host/usr`, `/run/host/etc/ld.so.cache` and so on.

    Available since 1.7.

  `host-etc`

    The host operating system's configuration from `/etc`.

    To avoid conflicting with the Flatpak runtime, this is mounted in the sandbox at `/run/host/etc`.

    Available since 1.7.

  `xdg-desktop`, `xdg-documents`, `xdg-download`, `xdg-music`, `xdg-pictures`, `xdg-public-share`, `xdg-videos`, `xdg-templates`

    freedesktop.org special directories. Available since 0.3.

  `xdg-desktop/`path``, `xdg-documents/`path``, etc.

    Subdirectories of freedesktop.org special directories. Available since 0.4.13.

  `xdg-cache`, `xdg-config`, `xdg-data`

    Directories defined by the freedesktop.org Base Directory Specification. Available since 0.6.14.

  `xdg-cache/`path``, `xdg-config/`path``, `xdg-data/`path``

    Subdirectories of directories defined by the freedesktop.org Base Directory Specification. Available since 0.6.14.

  `xdg-run/`path``

    Subdirectories of the `XDG_RUNTIME_DIR` defined by the freedesktop.org Base Directory Specification. Note that `xdg-run` on its own is not supported. Available since 0.4.13.

  `/`path``

    An arbitrary absolute path. Available since 0.3.

  `~/`path``

    An arbitrary path relative to the home directory. Available since 0.3.

  `~`

    The same as `home`. Available since 1.10. For better compatibility with older Flatpak versions, prefer to write this as `home`.

  One of the above followed by `:ro`

    Make the given directory available read-only.

  One of the above followed by `:rw`

    Make the given directory available read/write. This is the default.

  One of the above followed by `:create`

    Make the given directory available read/write, and create it if it does not already exist.

`persistent` (list)

  List of homedir-relative paths to make available at the corresponding path in the per-application home directory, allowing the locations to be used for persistent data when the application does not have access to the real homedir. For instance making ".myapp" persistent would make "~/.myapp" in the sandbox a bind mount to "~/.var/app/org.my.App/.myapp", thus allowing an unmodified application to save data in the per-application location. Available since 0.3.

`features` (list)

  List of features available or unavailable to the application, currently from the following list:

  `devel`

    Allow system calls used by development-oriented tools such as perf, strace and gdb. Available since 0.6.10.

  `multiarch`

    Allow running multilib/multiarch binaries, for example `i386` binaries in an `x86_64` environment. Available since 0.6.12.

  `bluetooth`

    Allow the application to use bluetooth (AF_BLUETOOTH) sockets. Note, for bluetooth to fully work you must also have network access. Available since 0.11.8.

  `canbus`

    Allow the application to use canbus (AF_CAN) sockets. Note, for this work you must also have network access. Available since 1.0.3.

  `per-app-dev-shm`

    Share a single instance of `/dev/shm` between all instances of this application run by the same user ID, including sub-sandboxes. If the application has the `shm` device permission in its `devices` list, then this feature flag is ignored. Available since 1.12.0.

  A feature can be prefixed with `!` to indicate the absence of that feature, for example `!devel` if development and debugging are not allowed.

`unset-environment` (list)

  A list of names of environment variables to unset. Note that environment variables to set to a value (possibly empty) appear in the [Environment] group instead.

### [Instance]

This group only appears in `/.flatpak-info` for a running app, and not in the metadata files written by application authors. It is filled in by Flatpak itself.

`instance-id` (string)

  The ID of the running instance. This number is used as the name of the directory in ``XDG_RUNTIME_DIR`/.flatpak` where Flatpak stores information about this instance.

`instance-path` (string)

  The absolute path on the host system of the app's persistent storage area in `$HOME/.var`.

`app-path` (string)

  The absolute path on the host system of the app's app files, as mounted at `/app` inside the container. Available since 0.6.10.

  Since 1.12.0, if flatpak run was run with the `--app-path` option, this key gives the absolute path of whatever files were mounted on `/app`, even if that differs from the app's normal app files.

  If flatpak run was run with `--app-path=` (resulting in an empty directory being mounted on `/app`), the value is set to the empty string.

`original-app-path` (string)

  If flatpak run was run with the `--app-path` option, this key gives the absolute path of the app's original files, as mounted at `/run/parent/app` inside the container. Available since 1.12.0.

  If this key is missing, the app files are given by `app-path`.

`app-commit` (string)

  The commit ID of the application that is running. The filename of a deployment of this commit can be found in `original-app-path` if present, or `app-path` otherwise.

`app-extensions` (list of strings)

  A list of app extensions that are mounted into the running instance. The format for each list item is `EXTENSION_ID=COMMIT`. If `original-app-path` is present, the extensions are mounted below `/run/parent/app`; otherwise, they are mounted below `/app`.

`branch` (string)

  The branch of the app, for example `stable`. Available since 0.6.10.

`arch` (string)

  The architecture of the running instance.

`flatpak-version` (string)

  The version number of the Flatpak version that ran this app. Available since 0.6.11.

`runtime-path` (string)

  The absolute path on the host system of the app's runtime files, as mounted at `/usr` inside the container. Available since 0.6.10.

  Since 1.12.0, if flatpak run was run with the `--usr-path` option, this key gives the absolute path of whatever files were mounted on `/usr`, even if that differs from the app's normal runtime files.

`original-runtime-path` (string)

  If flatpak run was run with the `--runtime-path` option, this key gives the absolute path of the app's original runtime, as mounted at `/run/parent/usr` inside the container. Available since 1.12.0.

  If this key is missing, the runtime files are given by `runtime-path`.

`runtime-commit` (string)

  The commit ID of the runtime that is used. The filename of a deployment of this commit can be found in `original-runtime-path` if present, or `runtime-path` otherwise.

`runtime-extensions` (list of strings)

  A list of runtime extensions that are mounted into the running instance. The format for each list item is `EXTENSION_ID=COMMIT`. If `original-app-path` is present, the extensions are mounted below `/run/parent/usr`; otherwise, they are mounted below `/usr`.

`extra-args` (string)

  Extra arguments that were passed to flatpak run.

`sandbox` (boolean)

  Whether the `--sandbox` option was passed to flatpak run.

`build` (boolean)

  Whether this instance was created by flatpak build.

`session-bus-proxy` (boolean)

  True if this app cannot access the D-Bus session bus directly (either it goes via a proxy, or it cannot access the session bus at all). Available since 0.8.0.

`system-bus-proxy` (boolean)

  True if this app cannot access the D-Bus system bus directly (either it goes via a proxy, or it cannot access the system bus at all). Available since 0.8.0.

### [Session Bus Policy]

If the `sockets` key is not allowing full access to the D-Bus session bus, then flatpak provides filtered access.

The default policy for the session bus only allows the application to own its own application ID, its subnames and its own application ID as a subname of `org.mpris.MediaPlayer2`. For instance if the app is called `org.my.App`, it can only own `org.my.App`, `org.my.App.*` and `org.mpris.MediaPlayer2.org.my.App`. It is only allowed to talk to names matching those patterns, plus the bus itself (`org.freedesktop.DBus`) and the portal APIs (bus names of the form `org.freedesktop.portal.*`).

Additionally the app is always allowed to reply to messages sent to it, and emit broadcast signals (but these will not reach other sandboxed apps unless they are allowed to talk to your app.

If the `[Session Bus Policy]` group is present, it provides policy for session bus access.

Each key in this group has the form of a D-Bus bus name or prefix thereof, for example `org.gnome.SessionManager` or `org.freedesktop.portal.*`.

The possible values for an entry are the following, in increasing order of access. Each value implies all the access from any lower values:

`none`

  The bus name is invisible to the application. Available since 0.2.

`see`

  The bus name can be enumerated by the application. Available since 0.2.

`talk`

  The application can send messages to, and receive replies and signals from, the bus name. Available since 0.2.

`own`

  The application can own the bus name. Available since 0.2.

### [System Bus Policy]

If the `sockets` key is not allowing full access to the D-Bus system bus, then flatpak does not make the system bus available unless the `[System Bus Policy]` group is present and provides a policy for filtered access. Available since 0.2.

Entries in this group have the same form as for the `[Session Bus Policy]` group. However, the app has no permissions by default.

### [Environment]

The [Environment] group specifies environment variables to set when running the application. Available since 0.3.

Entries in this group have the form `VAR=VALUE` where `VAR` is the name of an environment variable to set.

Note that environment variables can also be unset (removed from the environment) by listing them in the `unset-environment` entry of the [Context] group.

### [Extension NAME]

Runtimes and applications can define extension points, which allow optional, additional runtimes to be mounted at a specified location inside the sandbox when they are present on the system. Typical uses for extension points include translations for applications, or debuginfo for sdks. The name of the extension point is specified as part of the group heading. Since 0.11.4, the name may optionally include a tag in the NAME in the name@tag ref syntax if you wish to use different configurations (eg, versions) of the same extension concurrently. The "tag" is effectively ignored, but is necessary in order to allow the same extension name to be specified more than once.

`directory` (string)

  The relative path at which the extension will be mounted in the sandbox. If the extension point is for an application, the path is relative to `/app`, otherwise it is relative to `/usr`. This key is mandatory. Available since 0.1.

`version` (string)

  The branch to use when looking for the extension. If this is not specified, it defaults to the branch of the application or runtime that the extension point is for. Available since 0.4.1.

`versions` (string)

  The branches to use when looking for the extension. If this is not specified, it defaults to the branch of the application or runtime that the extension point is for. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.4.

`add-ld-path` (string)

  A path relative to the extension point directory that will be appended to LD_LIBRARY_PATH. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

`merge-dirs` (string)

  A list of relative paths of directories below the extension point directory that will be merged. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

`download-if` (string)

  A condition that must be true for the extension to be auto-downloaded. As of 1.1.1 this supports multiple conditions separated by semi-colons.

  These are the supported conditions:

  `active-gl-driver`

    Is true if the name of the active GL driver matches the extension point basename. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

  `active-gtk-theme`

    Is true if the name of the current GTK theme (via org.gnome.desktop.interface GSetting) matches the extension point basename. Added 0.10.1.

  `have-intel-gpu`

    Is true if the i915 kernel module is loaded. Added 0.10.1.

  `have-kernel-module-*`

    Is true if the suffix (case-sensitive) is found in `/proc/modules`. For example `have-kernel-module-nvidia`. Added 1.13.1.

  `on-xdg-desktop-*`

    Is true if the suffix (case-insensitively) is in the `XDG_CURRENT_DESKTOP` env var. For example `on-xdg-desktop-GNOME-classic`. Added 1.1.1.

`autoprune-unless` (string)

  A condition that must be false for the extension to be considered unused when pruning. For example, flatpak uninstall --unused and flatpak update use this information. The only currently recognized value is active-gl-driver, which is true if the name of the active GL driver matches the extension point basename. Available since 0.11.8.

`enable-if` (string)

  A condition that must be true for the extension to be enabled. As of 1.1.1 this supports multiple conditions separated by semi-colons. See `download-if` for available conditions.

`subdirectory-suffix` (string)

  A suffix that gets appended to the directory name. This is very useful when the extension point naming scheme is "reversed". For example, an extension point for GTK+ themes would be /usr/share/themes/$NAME/gtk-3.0, which could be achieved using subdirectory-suffix=gtk-3.0. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

`subdirectories` (boolean)

  If this key is set to true, then flatpak will look for extensions whose name is a prefix of the extension point name, and mount them at the corresponding name below the subdirectory. Available since 0.1.

`no-autodownload` (boolean)

  Whether to automatically download extensions matching this extension point when updating or installing a 'related' application or runtime. Available since 0.6.7.

`locale-subset` (boolean)

  If set, then the extensions are partially downloaded by default, based on the currently configured locales. This means that the extension contents should be a set of directories with the language code as name. Available since 0.9.13 (and 0.6.6 for any extensions called *.Locale)

`autodelete` (boolean)

  Whether to automatically delete extensions matching this extension point when deleting a 'related' application or runtime. Available since 0.6.7.

`collection-id` (string)

  The ID of the collection that this extension point belongs to. If this is unspecified, it defaults to the collection ID of the application or runtime that the extension point is for. Currently, extension points must be in the same collection as the application or runtime that they are for. Available since 0.99.1.

### [ExtensionOf]

This optional group may be present if the runtime is an extension.

`ref` (string)

  The ref of the runtime or application that this extension belongs to. Available since 0.9.1.

`runtime` (string)

  The runtime this extension will be inside of. If it is an app extension, this is the app's runtime; otherwise, this is identical to ref, without the runtime/ prefix. Available since 1.5.0.

`priority` (integer)

  The priority to give this extension when looking for the best match. Default is 0. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

`tag` (string)

  The tag name to use when searching for this extension's mount point in the parent flatpak. Available since 0.11.4.

### [Extra Data]

This optional group may be present if the runtime or application uses extra data that gets downloaded separately. The data in this group gets merged into the repository summary, with the xa.extra-data-sources key.

If multiple extra data sources are present, their uri, size and checksum keys are grouped together by using the same suffix. If only one extra data source is present, the suffix can be omitted.

`NoRuntime` (boolean)

  Whether to mount the runtime while running the /app/bin/apply_extra script. Defaults to true, i.e. not mounting the runtime. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.4.

`uri`X`` (string)

  The uri for extra data source `X`. The only supported uri schemes are http and https. Available since 0.6.13.

`size`X`` (integer)

  The size for extra data source `X`. Available since 0.6.13.

`checksum`X`` (string)

  The sha256 sum for extra data source `X`. Available since 0.6.13.

### [Policy SUBSYSTEM]

Subsystems can define their own policies to be placed in a group whose name has this form. Their values are treated as lists, in which items can have their meaning negated by prepending ! to the value. They are not otherwise parsed by Flatpak. Available since 0.6.13.

### [USB Devices]

USB devices can be enumerable or hidden by the USB portal as specified by the keys in this group. The vendor and product ids are validated by Flatpak, but aren't otherwise used or parsed. This merely grant the permission to enumerate USB device for use by the portal. This does give access to the devices. Available since 1.15.11.

`enumerable-devices` (string list)

  List of enumerable USB devices. Each element is the same syntax the arguments to `--usb`. Available since 1.15.11.

`hidden-devices` (string list)

  List of hidden USB devices, i.e. to remove the enumarable devices list. Each element is the same syntax the arguments to `--nousb`. Hidden devices take precedence over enumerable devices. Available since 1.15.11.

## Name

flatpak-remote — Configuration for a remote

## Description

Flatpak stores information about configured remotes for an installation location in `$installation/repo/config`. For example, the remotes for the default system-wide installation are in `$prefix/var/lib/flatpak/repo/config`, and the remotes for the per-user installation are in `$HOME/.local/share/flatpak/repo/config`.

Normally, it is not necessary to edit remote config files directly, the flatpak remote-modify command should be used to change properties of remotes.

System-wide remotes can be statically preconfigured by dropping flatpakrepo(5) files into `/usr/share/flatpak/remotes.d/` and `/etc/flatpak/remotes.d/`. Ifa file with the same name exists in both, the file under `/etc` will take precedence.

## File format

The remote config file format is using the same .ini file format that is used for systemd unit files or application .desktop files.

### [remote …]

All the configuration for the the remote with name NAME is contained in the [remote "NAME"] group.

The following keys are recognized by OSTree, among others:

`url` (string)

  The url for the remote. An URL of the form oci+https:// or oci+http:// is a Flatpak extension that indicates that the remote is not an ostree repository, but is rather an URL to an index of OCI images that are stored within a container image registry.

  For OCI remotes, client and CA certificates are read from `/etc/containers/certs.d` and `~/.config/containers/certs.d` as documented in containers-certs.d(5).

`gpg-verify` (boolean)

  Whether to use GPG verification for content from this remote.

`gpg-verify-summary` (boolean)

  Whether to use GPG verification for the summary of this remote.

  This is ignored if `collection-id` is set, as refs are verified in commit metadata in that case. Enabling `gpg-verify-summary` would break peer to peer distribution of refs.

`collection-id` (string)

  The globally unique identifier for the upstream collection repository, to allow mirrors to be grouped.

All flatpak-specific keys have a xa. prefix:

`xa.disable` (boolean)

  Whether the remote is disabled. Defaults to false.

`xa.prio` (integer)

  The priority for the remote. This is used when listing remotes, and when searching them for the runtime needed by an app. The remote providing the app is searched for its runtime before others with equal priority. Defaults to 1.

`xa.noenumerate` (boolean)

  Whether this remote should be ignored when presenting available apps/runtimes, or when searching for a runtime dependency. Defaults to false.

`xa.nodeps` (boolean)

  Whether this remote should be excluded when searching for dependencies. Defaults to false.

`xa.title` (string)

  An optional title to use when presenting this remote in a UI.

`xa.title-is-set` (boolean)

  This key is set to true if `xa.title` has been explicitly set.

`xa.comment` (string)

  An optional single-line comment to use when presenting this remote in a UI.

`xa.comment-is-set` (boolean)

  This key is set to true if `xa.comment` has been explicitly set.

`xa.description` (string)

`xa.description-is-set` (boolean)

  This key is set to true if `xa.description` has been explicitly set.

`xa.homepage` (string)

  An optional URL that points to a website for this repository to use when presenting this remote in a UI.

`xa.homepage-is-set` (boolean)

  This key is set to true if `xa.homepage` has been explicitly set.

  An optional URL that points to an icon for this repository to use when presenting this remote in a UI.

`xa.icon-is-set` (boolean)

  This key is set to true if `xa.icon` has been explicitly set.

`xa.default-branch` (string)

  The default branch to use when installing from this remote.

`xa.default-branch-is-set` (boolean)

  This key is set to true if `xa.default-branch` has been explicitly set.

`xa.main-ref` (string)

  The main reference served by this remote. This is used for origin remotes of applications installed via a flatpakref file.
