kolibri: 0.16.0 RC1 fails if Samba/Ansible/etc are installed (e.g. with python3-markdown) on the same OS

Confirmed on both Debian 12 and Ubuntu — here’s an example on a Debian 12.5 VM where the Kolibri 0.16.0 RC1 .deb was installed.

Logs below: Hopefully @rtibbles and @jredrejo can tell if a quick fix is possible or not!
