If we want to support Debian as a base for Kolab it might be wise to start building packages for Debian 13 (Trixie).

The following Distributions seem to be EOL - should we stop building packages for those?:

CentOS 7
Debian 8
Debian 9
RHEL7
Ubuntu 16.04
Ubuntu 18.04
Ubuntu 20.04

Debian 10&11 are EOL, but might still be supported by ELTS (https://wiki.debian.org/LTS/Extended)
