[debian-mysql] Bug#1035949: mariadb: upgrade issue: mariadb-server-10.5 fails to stop after all other -10.5 packages were removed

[Otto Kekäläinen]

I filed now https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests/47
as an exploration to fix this issue.

If we don't fix this in 10.11 the alternative would be to patch 10.5
and 10.3 to simply never fail on missing mariadb-client-10.3/5
package. I already did
https://salsa.debian.org/mariadb-team/mariadb-10.5/-/merge_requests/14
to make the problem have a proper error message users.
