Title:
  UnboundLocalError: local variable 'e' referenced before assignment in
  doUpdate, line 924

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

Bug description:
  Here's the message I got:

  if not e: 

  UnboundLocalError: local variable 'e' referenced before assignment 
  === Command detached from window (Wed Jul 23 19:26:09 2014) ===
  === Command terminated with exit status 1 (Wed Jul 23 19:26:19 2014) ===

  The problem persists also if I upgrade ubuntu-release-upgrader-core to
  the Utopic version of the software. This was easy to try as do-
  release-upgrade failed to restore my sources.list file to its previous
  state as it crashed and burned.
