Title:
  do-release-upgrade fails with confusing (gnu screen) message "Press x
  to destroy or r to resurrect window"

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  If do-release-update finds gnu screen installed, it will use it.
  However, if do-release-upgrade using screen fails, the screen shows:

      == Command terminated with exit status 1 (<date>) ==

  If you press any key, we then get the truly bizarre message:

      Press x to destroy or r to resurrect window

  I used gnu screen for quite a few years before moving to tmux and had
  never seen that message before. It is very unclear at this stage what
  is going on (aside from the fact the upgrade failed somehow) and what
  the correct response should be. In fact, initially, the assumption is
  that the message above is coming from do-release-upgrade itself which
  confuses further:

  - Does 'r' imply the failed upgrade will be retried?
  - What will 'x' destroy exactly? The window? The screen managed process? The upgrade attempt? My system?

  Is there some way we can avoid this rather scary message appearing, or
  atleast customize it to explain in simple terms what choices the user
  has I wonder?
