Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

I suggest trying:

sudo apt-get update
sudo apt-get -u dist-upgrade
sudo apt-get install -f
sudo apt-get -u dist-upgrade

Chances are good this will unstick whatever is wedged.

Good luck.
