[Simon Hausmann]

Attached the dist-upgrade apt.log that confirms that the issue seems to
be around the tk package

Title:
  Calculation of upgrade failed

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  kubuntu-devel-release-upgrade fails with the "Could not calculate the
  upgrade" message dialog, referring to an unresolvale problem while
  calculating the upgrade.

  A manual apt-get dist-upgrade on the terminal suggests that the
  following conflict might be the reason perhaps?

  Calculating upgrade... Failed
  The following packages have unmet dependencies:
   tk : Breaks: tk8.5 (< 8.5.14-3) but 8.5.11-2ubuntu4 is to be installed
  E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

  That said, aptitude seems to be able to determine an upgrade path.
