[Bug 876519] Re: Not able to upgrade from 11.04 to 11.10

[Matthew Paul Thomas]

Gabriel, thanks for providing so much info, and sorry we didn't get to
this bug report until now. Ubuntu 11.04 reached end-of-life on 28
October 2012, and Ubuntu 11.10 on 9 May 2013. So the next step is to
check whether the problem still happens with a current version of Ubuntu
(12.04, 12.10, or 13.04). One thing that would make testing easier for
other people would be instructions on how to set up a firewall that
blocks a particular package installed during upgrade.

Title:
  Not able to upgrade from 11.04 to 11.10

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  I started the upgrade manager (11.04 to 11.10) and had to stop during
  the "Getting new packages" part. I then later on re-started the
  process and libimobiledevice2 was upgradable, so I decided to upgrade
  it before finishing the system upgrade. Bad choice as now the system
  upgrade process stops doing anything at "Getting new packages"... I
  then tried downgrading libimobiledevice2 from 1.1.0-3ubuntu1 to
  1.1.0-3, but that doesn't help...

  While I agree that wasn't the best thing to do, I think in a system
  upgrade is stopped you should have a way of restarting it from scratch
  or continuing where it left off; currently it continues from what the
  UI says. I think it build an original list of packages to be upgraded
  and now it's stuck because of a mismatch.

  BTW, running "ubuntu-bug update-manager" stays stuck in the
  "Collecting problem information" step, and "ubuntu-bug" then choosing
  "other" closes with an error that a PID has to be given, even though
  there is no visible way of providing that.
