[Bug 1194964] Re: update-manager crashed with Package isn't installed in _run_in_dialog()

[Brian Murray]

** Description changed:

- This happened when I did an 'apt-get autoremove --purge' from the shell
- to free up space after update-manager had launched, causing a package
- that was in the upgrade list to be removed.  Since the apt database is
- not continuously locked while update-manager is running, it should
- gracefully handle changes to the installed package list between the time
- it displays the list and the time it applies the list to aptd.
