MySQL dependency problem after upgrading to KDE 4.3

[hkb]

After upgrading my KDE to 4.3 i started to get problems with my MySQL server and i cannot install new packages. I can upgrade but only if i force it. When i upgrade or install i get the following output:



_@_-desktop:~$ sudo apt-get -f install -V

I have Kubuntu 9.04.

Is there anyway to fix this so i can use my MySQL server again og use my system.

Have a look at the Thread..

I too have been having this problem...

I guess KDE requires mysql-server-5.0

If you have mysql-server-5.1 it asks to remove mysql-server-5.1 and install mysql-server-5.0

And when doing so it causes an error..

Greetings,

I found that /var/lib/mysql existed (despite the fact that no mysql-server of any version was installed.)

I checked using lsof and found that no processes were using files in it.
rm -rf /var/lib/mysql fixed it for me and I was able to install mysql-server-5.0 after that.

But...
That would remove all your Data with the Databases and Tables for your previous installation.

I couldn't afford to do that...

I was not sure if just copy pasting the same will work...
