Failed to update Ubuntu from 14.04 to 14.10.

[Zander Bolgar]

My Ubuntu was not fully working before I started the upgrade. I could not actually access my desktop - when I logged in I either got a black screen, an empty desktop, a desktop with icons (no dash), or no desktop (hang on login screen). I attempted the upgrade to fix it, but it failed.

Here is a picture of the failed update screen: http://i.imgur.com/txJ9PcL.jpg

you need to choose an active version: 12.10 have reached End Of Life a while back

You seem to have installed the cinnamon package on Ubuntu 13.10. Unfortunately, that package is not available yet for 14.04. To upgrade to Ubuntu 14.04 LTS you'll need to either wait for a fix for cinnamon to be available or uninstall the package and then upgrade.

The version number was a mistake (I've fixed it now). I was upgrading from 14.04 to 14.10.
