Today, it’s the time to switch to the next Ubuntu version. One interesting stuff in the latest distro, is the KDE4, but by default you still get a 3.5.9 revision..
Here a little tips to switch easily:
First uninstall the previous version
sudo apt-get remove --purge kdebase-bin-kde3 sudo apt-get autoremove --purge
sudo apt-get install kde4
As you can see, this is not really hard. The trick is to remove the old version cleanly.
