Bug#433865: update-manager: Reports updates are available, but cannot install chnages

[chrisg]

Package: update-manager
Version: 0.42.2ubuntu22-15
Severity: important


update-manager reports 10 updates available, pressing install updates
results in a dialog which says: -

Could not apply changes!
Fix broken packages first.

Checking in Synaptic reports: -

0 packages listed, 1635 installed, 0 broken. 0 to install/upgrade, 0 to
remove

Doing an update in synaptic (reload,mark all upgrades, apply) does not
resolve the problem.

The problem first reared it's head when I had some problems with 
texlive-base that I never got to the bottom of. As I didn't use the
package I just removed texlive-base (and kde) from my system.

I suspect that update-manager has some cached information about broken
packages (texlive-base), though I cannot seem to tell it that the
packages have been removed and are thus not broken any more.

A workaround for the problem in the shotr term would be very useful
thanks.
