Reviewing the files from your upgrade attempt you seem to have enabled
the xorg-edgers-ppa.  This will prevent the upgrade as that PPA contains
different versions of packages essential to Ubuntu.  The page,
https://launchpad.net/~xorg-edgers/+archive/ppa, contains details on to
how to revert to the official Xorg packages.  Thanks.

  I have ubuntu 13.10 and want to upgrade to 14.04.
  During calculation I get the error:

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

   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 ubuntu-release-upgrader-core' in a terminal.
