Please try installing ubuntu-gnome-desktop before trying to upgrade, and then try the upgrade process again and see if the matter gets sorted out.

I installed ubuntu-gnome-desktop and get the same results of unable to calculate upgrade.

Sorry,

I had forgotten to purge a nightly cinnamon ppa, purged and downgraded 23 packages and the upgrade is now working.
