Error when attempting to upgrade from Saucy to Trusty

[Christopher]

I can't update Saucy to Trusty.

"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."

I had a few things installed such as Steam and Splashtop, but after removing these applications and rebooting I still get this message.
