[Bug 571743] Re: system upgrade 9.10 --> 10.04 could not calculate upgrade when both xubuntu-desktop and ubuntu-desktop are installed

[Prateek Karandikar]

I still have the same issue in upgrading from 11.04 to 11.10 on a system
with both ubuntu-desktop and kubuntu-desktop installed. It first
complained about kubuntu-desktop, and aborted the upgrade, I removed it
and started the upgrade again, then it complained about update-manager-
kde (instead of complaining about everything at once and saving time!),
I removed that, and finally it has proceeded.

Title:
  system upgrade 9.10 --> 10.04 could not calculate upgrade when both
  xubuntu-desktop and ubuntu-desktop are installed

Status in “update-manager” package in Ubuntu:
  In Progress
Status in “update-manager” source package in Lucid:
  Fix Released

Bug description:
  TEST CASE:
  1. install xubuntu-desktop and ubuntu-desktop
  2. ensure that libsdl1.2debian-alsa is installed
  3. run do-release-upgrade
  4. verify that the upgrade can not be calculated
  5. run "do-release-upgrade --proposed
  6. verify that it can be calculated now

  Binary package hint: update-manager

  When running sudo update-manager -d from 9.10, error message appears
  as follows:

  first, here's the terminal dump -


  $ sudo update-manager -d
  extracting 'lucid.tar.gz'
  authenticate 'lucid.tar.gz' against 'lucid.tar.gz.gpg'
  tar: Removing leading `/' from member names
  WARNING: Failed to read mirror file

  now, the error message in the dialog box that pops up -

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade:
  The package 'ubuntu-desktop' is marked for removal but it is in the removal blacklist.

   This can be caused by:
   * Upgrading to a pre-release version of Ubuntu
   * Running the current pre-release version of Ubuntu
   * Unofficial software packages not provided by Ubuntu

  If none of this applies, then please report this bug against the
  'update-manager' package and include the files in /var/log/dist-
  upgrade/ in the bug report.

  Attached are the files from /var/log/dist-upgrade.
