[Lothar]

Public bug reported:

When updating in the UI (Muon) I get an error dialog saying

Unable to Mark Upgrades
Not all packages could be marked for upgrade.
...

Updating on the command line fails, too:

sudo aptitude safe-upgrade
Resolving dependencies...                
Unable to resolve dependencies for the upgrade: no solution found.
Unable to safely resolve dependencies, try running with --full-resolver.


$ sudo aptitude safe-upgrade --full-resolver
