Uninstall MySQL 5.1 impossible

[HHA]

Before the problem appears, I uninstalled MythTV-Frontend and -Backend. After the completed Process the Uninstall of MySQL failed.

Hi,

Relevant error:

It seems that the mysql server was running though:

Could you check if there is an init script for mysql in /etc/init.d/ (there shouldn't be any)?

Hi,
There is this file now:
-rwxr-xr-x 1 root root 5609 2010-02-08 23:20 /etc/init.d/mysql

But, I installed mysql from sources after the ubuntu package failed so I
might have put it there.

Regards,
Lars

The problem you're seeing may be related to the fact that you've installed mysql from sources. Marking the bug as Invalid - make sure that the Mysql from source installation has been correctly removed before reinstalling the mysql ubuntu package.

Hi,
My installation of mysql from sources was done after removing the ubuntu
package of mysql 5.1 and trying to install the ubuntu package of mysql
5.0. So I would say that my problem is not related to the sources
installation.

Downgrading from 5.1 to 5.0 is not supported. If you've purged mysql-5.1 you
should also make sure that the data directory (/var/lib/mysql) is empty before
installing mysql-5.0 - not that you may loose data by deleting /var/lib/mysql/
