Get ready for Debian 12 LTS

Based on https://lts-team.pages.debian.net/wiki/Development.html#switching-to-the-next-lts-release:

  • Send a reminder to debian-lts-announce@lists.debian.org two months before the official support for the last LTS ends (bullseye).
  • Contact the Teams/Publicity and draft an announcement that the old LTS release cycle will come to an end (in 2026-08-31) and a new one has started. Example, Example 2
  • Contact the Stable Release Managers for coordinating the date of the last point release (and so that they can clean up the proposed updates queues).
  • Ensure that the infrastructure is ready for the new LTS release:
    • Contact the FTP master team to ask them to open the oldstable-security upload queue when we take over from the Security Team.
  • Contact the FTP team and ask them to wait four weeks with archiving the old LTS release to give users a "grace period" to update their systems.
  • Contact the Buildd team to ask them to shutdown the build queues for the old LTS release.
  • Request from the Security Team a copy of the oldstable build logs, remove from them the logs of non-LTS architectures, and ask the Wanna-build team to make them (the LTS-related logs) public. (example e-mail)
  • Update all relevant pages especially LTS/Using, LTS/Installing and this LTS/Development itself.
  • Check/update/merge security-support.deb12 in debian-security-support
  • Update/verify the contents of data/packages/lts-do-call-me and data/packages/lts-do-not-call in the security tracker.
  • Reference pending proposed-updates in data/dla-needed.txt to prevent conflicts
