[Bug 907167] Re: Update-manager isn't able to upgrade distro from Natty to Oneiric

[Tim]

Looks like the upgrade is being halted by a custom PPA.  Probably xorg,
if I am correct.  You need to remove that PPA and its packages to
continue.  Consider the tool 'ppa-purge'.

Closing report since its not a bug, but feel free to continue commenting
here if you have any problems.

Title:
  Update-manager isn't able to upgrade distro from Natty to Oneiric

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

Bug description:
  This is what I get when I try to upgrade my distro :

  """
  An unresolvable problem occurred while calculating the upgrade:
  E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

   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 using the command 'ubuntu-bug update-manager' in a terminal.
