Title:
  Ubuntu won't upgrade to next version

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  1) Version: Ubuntu 14.04.3 LTS

  2) Package version: ubuntu-release-upgrader-core 1:0.220.8

  3) Expected Results: Installed Ubuntu 14.04 LTS since it was the only
  disk I had, and expected to upgrade to latest version of Ubuntu by
  telling Ubuntu to notify me of any new version instead of staying on
  the LTS channel.

  4) Actual Results: Unfortunately, the upgrade tool doesn't want to work for whatever reason, stating that I'm on a pre-release channel or something along those lines. Either way, I am unable to migrate to the next newest version of Ubuntu. 
  *NOTE* When I performed the fresh install of Ubuntu 14.04 LTS, I chose not to download updates or install restricted packages... Don't know if that had an effect on the problem...
