## Installation and configuration

### Supported distributions

The LemonLDAP::NG team supports running our software in the following distributions:

- Debian

- Ubuntu

- RHEL and derivatives (Rocky Linux, AlmaLinux, etc.)

We release new versions of LemonLDAP::NG for all, currently community-supported versions of these distributions. If you need LemonLDAP::NG to work on a different distribution, or on an older version, please contact one of our contributing sponsors.

### Long Term Support

LL::NG Team maintains these versions following a “Long Term Support” policy: these versions are maintained without software updates by transposing only security fixes.

Version LTS | Secured | Limit
--- | --- | ---
2.16.x |  | June 2028
2.21.x |  | June 2030

### Packaged versions

These versions are maintained under distribution umbrella following their policy.

#### Debian

Tip

Following Debian Policy, LL::NG packages are never upgraded in published distributions. However, security patches are backported by maintenance teams (except some minor ones). See Security tracker

Possible Extended LTS

updated by LL::NG Team until dependencies are compatible. Don’t use backports unless you plan to update your system because backports are not covered by Debian Security Policy

few days after release

Ubuntu universe/multiverse branches are community maintained (so not maintained by Canonical), but in fact nobody considers LL::NG security issues. See this issue for example
