DNF5-VERSIONLOCK(8)

NAME
dnf5-versionlock - Versionlock Command

SYNOPSIS

dnf5 versionlock <subcommand> <package-spec-N>...

DESCRIPTION

The versionlock command in DNF5 takes a set of names and versions for packages and excludes all other versions of those packages. This allows you to protect packages from being updated by newer versions. Alternately, it accepts a specific package version to exclude from updates, e.g. for when it's necessary to skip a specific release of a package that has known issues.

The plugin will walk each entry of the versionlock file, and exclude any package of given name that doesn't match conditions listed within the file. This is basically the same as using dnf5 --exclude for the package name itself (as you cannot exclude installed packages), but dnf will still see the versions you have installed/versionlocked as available so that dnf reinstall will still work.

Note the versionlock command does not apply any excludes in non-transactional operations like repoquery, list, info, etc.

SUBCOMMANDS

    add
        Add a versionlock for all available packages matching the spec. It means that only versions of packages represented by package-spec-N are available for transaction operations. The NEVRAs to lock to are first searched among installed packages and then (if none is found) in all currently available packages.

    exclude
        Add an exclude (within versionlock) for the available packages matching the spec. It means that packages represented by package-spec-N will be excluded from transaction operations.

    clear
        Remove all versionlock entries.

    delete
        Remove any matching versionlock entries.

    list
        List the current versionlock entries.

EXAMPLES

    dnf5 versionlock add acpi
        If acpi package is installed, lock it to currently installed version. If it's not installed, lock acpi to any of currently available versions.

    dnf5 versionlock list
        Show current versionlock configuration.

    dnf5 versionlock delete acpi
        Remove any rules for acpi package.

    dnf5 versionlock exclude iftop-1.2.3-7.fc38
        Exclude iftop-1.2.3-7.fc38 release.

VERSIONLOCK FILE FORMAT

The versionlock file is a TOML file stored in location /etc/dnf/versionlock.toml. The file must contain the version key, currently supported version is 1.0. Then it contains packages - a list of locking entries. Each entry consist of the package name and a list of conditions. The package name specification supports the same glob pattern matching as the shell. All the conditions must be true for a package to match (they are combined using logical AND). All entries are then combined together using logical OR operation.

  Example of versionlock file

            version = "1.0"

            # keep package bash on version 0:5.2.15-5.fc39
            [[packages]]
            name = "bash"               # name of the package
            comment = "description"     # optional description of the entry
            [[packages.conditions]]     # conditions for the package "bash"
            key = "evr"                 # epoch, evr, and arch keys are supported
            comparator = "="            # <, <=, =, >=, >, and != operators are supported
            value = "0:5.2.15-5.fc39"   # pattern to match

            # exclude iftop-1.2.3-7.fc38 version (versionlock exclude iftop-1.2.3-7.fc38)
            [[packages]]
            name = "iftop"
            [[packages.conditions]]
            key = "evr"
            comparator = "!="
            value = "0:1.0-0.31.pre4.fc39"

            # keep acpi on major version 3
            [[packages]]
            name = "acpi"
            [[packages.conditions]]
            key = "evr"
            comparator = "<"
            value = "4"
            [[packages.conditions]]
            key = "evr"
            comparator = ">="
            value = "3"

            # keep all *nvidia* packages on version 3:570.*
            [[packages]]
            name = "*nvidia*"
            [[packages.conditions]]
            key = "evr"
            comparator = ">="
            value = "3:570"
            [[packages.conditions]]
            key = "evr"
            comparator = "<"
            value = "3:571"
