Knoppix 3.2 KDE Upgrade ??

Hi there,

I installed Knoppix 3.2, the CeBIT Edition (26?) successfully to the harddisk.

Now I wanted to play around with kroupware.

Has anyone here successfully upgraded KDE from 3.1 to 3.11 ?
Everytime I try this, apt-get says an upgrade is not possibe, and wants just to remove the complete KDE package, not to upgrade it.

This might be an issue with "uncleanly build" .deb-packages, but I cannot believe that this just isn't working, so is there a trick, maybe in the installation order?

Thank you very much in advance.
