Re: MariaDB Server is not installing on Debian 12

[Cosmin Humeniuc <cosmin@hume.ro>]

I have the same problem of not being able to install mariadb-server 
1:10.11.2-1. The error is the same - a failed attempt to stop 
mariadb.service or mysql.service.

In my case, there is no service running for either of them, so I have 
nothing to stop. I also checked, and there's no mariadb.preinst file in 
/var/lib/dpkg/info.

However, I started from these lines in the output:
> Errors were encountered while processing:
>  /var/cache/apt/archives/mariadb-server_1%3a10.11.2-1_amd64.deb

and I used dpkg-deb to look in that package file. DEBIAN/preinst had a 
`stop_server()` function that was trying to stop existing servers based 
on the result of:
> pgrep -x --nslist pid --ns $$ "mysqld|mariadbd"

(at line 31). I executed that in a shell and I did get a result - only 
it wasn't for a running server, but for a standalone process:
> pgrep -x --nslist pid --ns $$ "mysqld|mariadbd"
> 1939

> ps aux | grep 1939
> cosmin      1939  0.0  1.2 2439604 204892 ?      Sl   19:22   0:02 
/usr/sbin/mysqld 
--defaults-file=/home/cosmin/.local/share/akonadi/mysql.conf 
--datadir=/home/cosmin/.local/share/akonadi/db_data/ 
--socket=/run/user/1000/akonadi/mysql.socket 
--pid-file=/run/user/1000/akonadi/mysql.pid

My guess is that the check from `preinst` could be improved to handle 
cases like this. Does it count like a bug? Should I file a report?
