[Bug 758013] Re: apt-clone crashed with SystemError in _restore_package_selection_in_cache(): E:Unable to correct problems, you have held broken packages.

[Erick Brunzell]

I need to do quite a bit more testing .............. hopefully between
Oneiric Alpha 3 and Beta 1 ............... but I repeated a test and
everything worked fine.

I think what might be happening is that "apt-clone" fails if there are
packages from sources such as the partner or Medibuntu repos installed
during the upgrade.

But I do need to run several more tests to see if I can actually
duplicate the behavior of both successful live upgrades and unsuccessful
live upgrades :^)

I will try hard to give this some priority but I'm mired down in some
remodeling ATM.
