What did work is not a "fix" to bug, but a work around. Apparently, [libnss3-1d] attaches itself (through upgrades) to old packages. As such, [sudo apt-get autoremove] does not remove these packages. I found this out by installing the [libnss3-1d] deb file listed above. Then opened [synaptic] which reported a broken [libnss3-1d] package. Clicking to repair the broken package, It listed everything it was attached to. This included Thunderbird and Network Manager, in addition to old lucid packages. All these packages had to be removed and reinstalled, minus the old lucid packages, and on reboot - the upgrade succeeded.
What the upgrade manager failed to do - find and delete old packages, that may (and do) cause upgrade problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775289 Title: E:Error, pkgProblemResolver::Resolve generated breaks, caused by held packages.
