This is a real blocker - so... Multi-Desktop environment (still recommended?) puts interested peoples desktop in a unsecure state as it blocks APT then.
If there is no other solution we will have to ask to remove Telepathy from Kubuntu-meta or _not_ to recommend a mixed Desktop-Environment any longer & put up a warning. May sound harsh, but...
This error covers two release + a third that's in current development.
A possible solution to get at least APT back into it's shoes again was posted in askubuntu:
