Hello guys,

i am running Ultimate Edition 3.4 with 12.04... then i decided to upgrade so it upgraded to 12.10
now it ruined my Ultimate Edition and i am trying to upgrade again to the 13.10 but i keep on getting errors

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

i really hate to reinstall and i just wanted to upgrade and keep my Ultimate Edition or upgrade it...

anything else i can do to fix my Ultimate Edition and upgrade it? and can i upgrade to 3.8 ?
btw my DVD rom doesn't work so i can only use USB.
