Public bug reported:
I tried to run `sudo do-release-upgrade -d`, and stumbled into problems
with:
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be
caused by held packages.
I used ppa-purge to get rid of a couple of PPA's used at that time, but
it didn't help (and shouldn't, update-manager takes care of 3rd party
software sources, right?).
Looked into /var/log/dist-upgrade/main.log, I see only one interesting
line:
2012-03-31 23:18:49,581 DEBUG failed to SystemUnLock() (E:Not locked)
...but I'm attaching it anyway. Much, much more interesting is the
/var/log/dist-upgrade/apt.log, which shows a number of broken packages.
Attaching it too, obviously.
