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

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

Other¶
| [1] | (1, 2) Possible Extended LTS |
| [2] | 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 |
| [3] | (1, 2) few days after release |
| [4] | 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 |
