Title:
  UpgradeStatus can be incorrect

Status in apport package in Ubuntu:
  Confirmed

Bug description:
  In the general hook for ubuntu there is the following code:

      log = '/var/log/dist-upgrade/main.log'
      if os.path.exists(log):
          mtime = os.stat(log).st_mtime
          human_mtime = time.strftime('%Y-%m-%d', time.gmtime(mtime))
          delta = time.time() - mtime

          # Would be nice if this also showed which release was originally installed
          report['UpgradeStatus'] = 'Upgraded to %s on %s (%d days ago)' % (release_codename, human_mtime, delta / 86400)
      else:
          report['UpgradeStatus'] = 'No upgrade log present (probably fresh install)'

  This does no checking of main.log to see if the upgrade was actually
  successful, so if someone is reporting a bug about a failed upgrade of
  ubuntu-release-upgrader they'll have a confusing 'UpgradeStatus' of
  today for the previous release.
