Debian 11 Long Term Support reaches end-of-life

August 31st, 2026

The Debian Long Term Support (LTS) Team hereby announces that Debian 11 bullseye support has reached its end-of-life today, 31 August 2026, five years after its initial release on 14 August 2021.

Starting in September, Debian will not provide further security updates for Debian 11. A subset of bullseye packages will be supported by external parties. Detailed information can be found at Extended LTS.

The Debian LTS Team is currently providing security support for Debian 12 bookworm, the current oldstable release. Thanks to the combined efforts of different teams including the Security Team, the Release Team, and the LTS Team, the Debian 12 life cycle encompasses five years. Debian 12 will receive Long Term Support until 30 June 2028. The supported architectures in Debian 12 LTS are amd64, i386, arm64, armhf and ppc64el.

For further information about using bookworm LTS and upgrading from bullseye LTS, please refer to LTS/Using.

Debian and its LTS Team would like to thank all contributing users, developers, sponsors and other Debian teams who are making it possible to extend the life of previous stable releases, and who have made Bullseye LTS a success.

If you rely on Debian LTS, please consider joining the team, providing patches, testing or funding the efforts.
