Debian 12 -- Errata

Security issues

Debian security team issues updates to packages in the stable release in which they've identified problems related to security. Please consult the security pages for information about any security issues identified in bookworm.

If you use APT, add the following line to /etc/apt/sources.list to be able to access the latest security updates:

  deb bookworm-security main contrib non-free non-free-firmware

After that, run apt update followed by apt upgrade.

Point releases

Sometimes, in the case of several critical problems or security updates, the released distribution is updated. Generally, these are indicated as point releases.

See the ChangeLog for details on changes between 12 and 12.1.

Fixes to the released stable distribution often go through an extended testing period before they are accepted into the archive. However, these fixes are available in the dists/bookworm-proposed-updates directory of any Debian archive mirror.

If you use APT to update your packages, you can install the proposed updates by adding the following line to /etc/apt/sources.list:

  # proposed additions for a 12 point release
  deb bookworm-proposed-updates main contrib non-free-firmware non-free

After that, run apt update followed by apt upgrade.
