Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Please note that (I think) the upgrade is failing because it's attempting to upgrade to Ubuntu 14.10 (utopic) which is a no longer supported release. This is due to the configuration file for update-manager being set to:

  Prompt=normal

Adjust this to

  Prompt=lts

to get update-manager to upgrade to Ubuntu 16.04 (Xenial). You can do this either through an editor, or through the "Software and Updates" tool; at the bottom of the Updates tab, there is a setting "notify me of a new ubuntu version" -- select "For long-term support versions".

Additionally, your file /etc/apt/sources.list is already configured for the release you wanted to upgrade to (utopic) so in addition to Steve's comment you'll also want to change /etc/apt/sources.list back to trusty.
