Trusty Tahr upgrade chokes, apparently on cinnamon

[Kirk Lowery]

Error message: "An unresolvable problem occurred while calculating the upgrade." I'm not running a pre-release version of 13.10, so the last possibility applies: "Unofficial software packages not provided by Ubuntu".

If I understand the debug information correctly, cinnamon and related packages bother the upgrader.

Requested info:

Release: up-to-date version 13.10
Package: Trusty Tahr upgrader; latest version
Expected results: successful upgrade
Actual results: abnormal ending; error messages reported above
