Comment 18 for bug 930499

Upgraded from 11.10. During install I unticked the download updates while installing. Initial install complained about not being able to upgrade all packages.

Once upgraded 'finished' -- I rebooted and logged into Ubuntu.

* Installed synaptic package manager.
    * Added canonical partner repositories.
    * Clicked Synaptic "Reload" button -- then it crashed -- suggesting I report a bug if problems persist but that it may be due to outdated packages. (sorry, going off memory)

* So then, I selected Updated Manager from the Dash. Also complained about out-dated packages -- and suggested partial upgrade.
* I ran partial upgrade. (walked away for 30min)
* Came back to an error installing something (clicked on more details and got an error 'permission denied' when trying to access report)
* In a background dialog, also had error message couldn't update CUPS. (perhaps that was the previous problem?)
* Upgrade continued. suggested removing two unneeded packages... so I did. finished 'successfully.'
* rebooted
* attemted to login to run update-manager again, and dash unresponsive -- here I am.
