Debian 11 ’Bullseye’ Enters Long Term Support Phase
Debian, one of the most esteemed and widely used Linux distributions, has transitioned its version 11, codenamed ‘Bullseye,’ from regular security updates to a Long Term Support (LTS) phase as of August 15, 2024. This shift comes exactly three years after its initial release.
Adding two updates:

Debian -- News -- Security support for Bullseye handed over to the LTS team
Bullseye LTS will be supported from 15 August 2024 to 31 August 2026.
Whenever possible, users are encouraged to upgrade their machines to Debian 12, alias "Bookworm", the current Debian stable release. To make the life cycle of Debian releases easier to remember, the related Debian teams have agreed on the following schedule: three years of regular support plus two years of Long Term Support. Debian 12 will receive thus regular support until 10 June 2026 and Long Term Support until 30 June 2028, three and five years after the initial release, respectively.
Users that need to stick with Debian 11 can find relevant information about Debian Long Term Support at LTS/Using. Important information and changes regarding Bullseye LTS specifically can be found at LTS/Bullseye.
Debian 11 LTS users are invited to subscribe to the announcement mailing list for receiving notifications about security updates, or to follow the latest advisories through the LTS Security Information webpage.
Debian LTS Team takes over Debian 11 security updates from today - Neowin
The Debian Project has announced that the Debian Long Term Support (LTS) Team is taking over security support for Debian 11 now that it is three years old. The LTS Team takes over this responsibility from the Security and Release Teams, which can now focus on the current Debian 12 and soon-to-be-released Debian 13.
Now that the LTS Team has taken over Debian 11 updates, users can continue using it until August 31, 2026. With that said, the announcement recommends that people upgrade their machine to the current stable, Debian 12. This LTS phase will give anyone who needs it time to upgrade more graciously if they have a lot of data that needs backing up, etc. It's best not to wait until August 2026 to upgrade, though.
