System kann nicht auf UCS 5.0 ugedatet werden

Wollte auf UCS 5.0 updaten.
Scheinbar Reste von KDE auf System vorhanden.
Wie kann man KDE endgültig deinstallieren?
Welche Befehle braucht man?
Bin ziemlicher Laie.

Anbei das Log von der fehlgeschlagenenen Routine.

The system can not be updated to UCS 5.0 due to the following reasons:

Hi,

eigentlich steht schon alles da was man braucht … :slight_smile:

Use “univention-remove --purge” with the packages as following arguments to remove them

Probier mal:
univention-remove --purge univention-kdm
das gleiche dann noch für “univention-mozilla-firefox” und “univention-x-core”
