[debian-mysql] Bug#1004262: mariadb-server: Instead of being upgraded, mariadb-server gets removed after apt update

[Rutger van Sleen]

Package: mariadb-server
Version: 1:10.5.12-1
Severity: important

Dear Maintainer,

mariadb-server-10.6 has hit testing, after `apt update` I found that
`apt full-upgrade` want to remove mariadb-server package, along with the
10.5 packages

I have mariadb-server manually installed, to keep my system up to date
when a new version of mariadb-server-?? hits the repository. I expected
that mariadb-server-10.6 would be installed, but that didn't happen.

What puzzles me, is that I don't see any reason why the metapackage 
mariadb-server gets removed, there is clearly a new candidate for it.
