Well not an expert here, but 10.10 is at it's End OF Life(EOL) and i'm not sure if canonical supports upgrading from a unsupported version. I hope this link helps

I would try the Upgrading Using the Alternate CD/DVD method on that page.

Download a live CD and boot from it. It will give you the option to upgrade previous ubuntu install. This way you can directly upgrade to 12.04 (which will be final in a week).
