If the workarounds above didn't work, why do you think that's the same bug at all? I think you should open a new report.
The other issue is that if you actually upgraded your system using 'apt-get upgrade' (not even 'dist-upgrade'?!), that's not the correct procedure and is likely to break. See https://help.ubuntu.com/community/LucidUpgrades.
