It was autoremoved when the new kernel was installed. Reinstall it if it is still available in the repository.

apt-get install linux-image-6.0.0-6-amd64

$ sudo apt-get install linux-image-6.0.0-6-amd64
Paketlisten werden gelesen… Fertig
Abhängigkeitsbaum wird aufgebaut… Fertig
Statusinformationen werden eingelesen… Fertig
Paket linux-image-6.0.0-6-amd64 ist nicht verfügbar, wird aber von einem anderen Paket
referenziert. Das kann heißen, dass das Paket fehlt, dass es abgelöst
wurde oder nur aus einer anderen Quelle verfügbar ist.

E: Für Paket »linux-image-6.0.0-6-amd64« existiert kein Installationskandidat.
i do not know how to have the error output in english

Prefix the command with LANG=C
It seems that kernel 6.0 is not available any more in testing/sid.
linux-image-6.0.0-0.deb11.2-amd64 is still available in bullseye-backports.

Because they are not maintained any more. This is testing/unstable, not stable. If you want stability, use the stable distribution.

Packages installed manually won't be autoremoved.
List automatically installed packages:

Code: Select all

apt-mark showauto linux-image-*
List manually installed packages:

Code: Select all

apt-mark showmanual linux-image-*
Mark packages as manually installed:

Code: Select all

apt-mark manual <package> <package>...
