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.

Hi IMO this is a dup of 500175.
TL;DR a rare but so far every now and then reoccuring issue.
You just got the error report on reboot, it actually is affecting your upgrades.

If you have no issue updating packages, then all is fine and this was a one-off case.
I'll mark this as a dup now ...
