I have this problem.

You did an Debian Upgrade or what exactly ?

And this is YOUR config ?

Code:

/etc/mysql/debian.cnf

is there was an upgrade of debian


[quote]And this is YOUR config ?

Code:

/etc/mysql/debian.cnf

[client]
host = localhost
user = debian-sys-maint
password =
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
user = debian-sys-maint
password =
socket = /var/run/mysqld/mysqld.sock
basedir = /usr

if reinstall mysql?

[BeNe]

This is your complete MySQL-Server config ?
A litte bit short or ?
The "datadir" and the "port" is missing for example.
Please check if there exist a Backup file in the /etc/mysql/ directory.

Fine!
This file(my.conf) looks much better than the other (debian.cnf).
Try to start the MySQL-Server with the my.conf
