If your organization is running production systems on Debian 11 (“bullseye”), you should be aware that the Debian project’s security support (as committed at the time of release) will end on 31 August 2026.
If upgrading to a newer release of Debian is not an option at this time, you can maintain the server security by subscribing to Freexian’s Extended LTS.
Along with Debian 11, Freexian’s Extended LTS currently supports Debian 9 (“stretch”) until 30 June 2027 and Debian 10 (“buster”), until 30 June 2029.
We would like to invite organizations using more recent Debian releases to consider sponsoring the Debian LTS team. Your support will help fund the Debian LTS team, that recently took over the security maintenance of Debian 12 (“bookworm”) from the regular Debian security team in June 2026.
