What to do now that Debian 11 is end of life
Running an end-of-life release means new vulnerabilities in the kernel, browser libraries, and system packages stay unpatched. If you cannot upgrade yet, extended support runs until Jun 30, 2031, usually as a paid service. The next supported step is Debian 12, supported until Jun 30, 2028.
Upgrade one release at a time: point your APT sources to the next codename, then run sudo apt upgrade --without-new-pkgs and sudo apt full-upgrade. Read the release notes before starting.
