Title:
  Unable to upgrade to 15.10 from 15.04

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

Bug description:
  Upgraded system from 14.04 then to 15.04 (it seemed to skip 14/10). I
  run do-release-upgrade to check for an update and it wont update to
  15.10.

  I did at one point accidentally do the release upgrade to 16.04 but I
  stopped it before the first prompt to download anything.

  cat /etc/lsb-release 
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=15.04
  DISTRIB_CODENAME=vivid
