[debian-mysql] Bug#990708: Bug#990708: mariadb-server-10.5: upgrade problems due to galera-3 -> galera-4 switch

[Otto Kekäläinen]

Hello!

I was able to reproduce this, and addressed it in
https://salsa.debian.org/mariadb-team/galera-4/-/commit/27a142792b5e02e66b8f1adf9a7b896c5722dd17
+ added Salsa-CI testing for this specific scenario so that it would
not regress again, but seems there is still some second scenario that
does not upgrade properly.

I wish somebody could contribute with exact steps on how to reproduce
the issue. So far I've gotten some half attempts at that but they
haven't been actionable for me.


My plan was to keep Galera-3 in Debian stable / Ubuntu stable as for
the duration that MariaDB 10.3 is supported upstream, as MariaDB does
not offer Galera by themselves, so it is better to have it available
in distro.
