[debian-mysql] Bug#988089: MariaDB upgrade issues from Debian 10 to Debian 11

[Otto Kekäläinen]

Hello!

I triaged all MariaDB bugs in Debian today and noticed the following
bug reports are very similar:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988089
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976147
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977137

I request your help to test, debug and fix the MariaDB 10.3 -> 10.5
upgrade issues you have experienced.

The better you can reproduce the issues, the easier they are to
investigate. Ideally somebody would write an extension to our current
https://salsa.debian.org/mariadb-team/mariadb-10.5/-/blob/master/debian/salsa-ci.yml
which would test the upgrade scenario on every commit and thus verify
when the issue is fixed, and prevent it from re-surfacing in the
future.

Here is a debian-devel thread where I learnt new ways to run apt in
debug mode to better see why it chooses to upgrade/remove certain
packages, it might be helpful here too:
