Title:
  interrupted release upgrade may confuse update-manager into believing
  an upgrade is not necessary

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

Bug description:
  About halfway through getting new packages (1,017+ of 2,045), in an Distribution Upgrade (`sudo update-manager -d`) to 14.04, I lost my wireless access connection.
  The net access had been flaky and I hold Ubiquity blameless in the dropped connection.

  The issue was I was unable to get Ubiquity to continue on. About this
  system still showned 13.10 and `update-manager -d` stated there where
  no updates. I kinda expected a restart to pick up the ball but it
  didnot, nor did a full power restart.

  I am not in any position to be able to recreate the issue, though I
  believe that just pulling the network connection while the system is
  fetching files will manifest what happened to me.

  I had been logging the progress of the file being fetched prior to
  losing the connection. My last manual entry was recording that
  Ubiquity was "Fetching file 1,083 of 2,045 at a blazing 217 kB/s "
