Bug#1151058: [debian-mysql] Bug#1151058: mariadb-server: socket activation restarts server mid-upgrade; stalled instance blocks service (SendSIGKILL=no)

[José Miguel Gonçalves]

Hi,

I've opened a merge request with a fix:
https://salsa.debian.org/mariadb-team/mariadb-server/-/merge_requests/187

preinst stops mariadb.socket before the service, and postinst starts it
again only if it was active. It adds an autopkgtest for the upgrade cases,
which passes on Salsa CI.

Regards,
