[Bug 1342308] Re: do-release-upgrade -p failed to upgrade my system

[Dilton McGowan II]

After painstakingly going through my package list that was installed in
12.04 LTS I found that these two packages apparently can't be installed
together on 14.04:

gnuplot-nox					install
gnuplot-x11					install

Using Synaptic which I trust to give me more details, I find that either
can be installed but not both or not both in a single file that I use
for Read Markings.

Whether those broke the upgrade from 12.04 LTS to 14.04 LTS, I'm not
sure.

  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.
