[Bug 1052605] Re: ERROR:root:getListFromFile: no '/usr/share/update-manager/removal_blacklist.cfg' found: exception during Precise to Quantal upgrade on amd64+mac

[Michael Vogt]

This means:
1. when updating sources.list  but not installing any packages it should revert the system state again
2. when the lock is taken it should at either show a message or keep spinning on it for some seconds at least

  ubuntu-bug update-manager also is also crashing possibly due to the upgrade being unsuccessful. That means no other logs could be attached.
