Thank you for taking the time to report this bug and helping to make Ubuntu better. The release upgrade process will now try to upgrade from 14.04 (Trusty) to 15.04 (Vivid) as 14.10 (Utopic) is End of Life. Could you please try the upgrade process again and if it fails open a new bug report following the same process you used to open this one? Thanks in advance!
