[Bug 1001796] Re: error msg: Could not calculate the upgrade

[Jean-Baptiste Lallement]

Please remove video drivers from the xorg-edgers ppa before trying the
upgrade again. ppa-purge may help you to revert to the official version
of the packages.

I'm closing this report because it is not a bug with Ubuntu. Don't
hesitate to file any bug you may find.

  An unresolvable problem occurred while calculating the upgrade:
  E:Unable to correct problems, you have held broken packages.
   This can be caused by:
   * Upgrading to a pre-release version of Ubuntu
