[debian-mysql] Bug#861782: mariadb-server-10.1: Upgrade fails because mariadb-server-10.1.prerm fails to stop mysqld.

[chris]

Package: mariadb-server-10.1
Version: 10.1.22-4
Severity: important

Dear Maintainer,

Upgrade from 1 month old version failed.

Installation says:

There is a MySQL server running, but we failed in our attempts to stop it.
Stop it yourself and try again!

and fails.

When looking at:
/var/lib/dpkg/info/mariadb-server-10.1.prerm
one can see:
invoke-rc.d mysql stop
pidof -c /usr/sbin/mysqld

Executing those lines myself, I get:
# invoke-rc.d mysql stop; pidof -c /usr/sbin/mysqld
3174

Similarly:
# systemctl stop mariadb.service; pidof -c /usr/sbin/mysqld
3174

However I could stop the sever as a plain user:
$ akonadictl stop

Verify it is stopped:
# pidof -c /usr/sbin/mysqld

Then the upgrade worked flawlessly:
# apt-get upgrade

A very verbose description can be found there:

Best,
Chris
