Bug description:
  Title: No pop-up window to warn users that system should not reboot or
  shutdown while installing security updates

  Summary:
  No pop-up window to warn users that system should not reboot or shutdown while installing security updates

  Steps:
  1. trigger unattended-upgrades
  2. reboot or shutdown system while installing packages

  Expected results: There is a pop-up window to warn users that system
  should not reboot or shutdown

  Actual results: There is no pop-up window to warn users

  Additional information:
  $ apt-cache policy unattended-upgrades
  unattended-upgrades:
    Installed: 0.90
    Candidate: 0.90ubuntu0.5
  $ lsb_release -rd
  Description:    Ubuntu 16.04 LTS

  
  * APT SRU *
  [Impact]
  Stopping apt-daily-upgrade.service terminates dpkg and friends by sending the signals to all processes in the cgroup, and will send KILL quickly after.

  [Test case]
  Start apt-daily-upgrade.service and stop it while unattended-upgrades is running.

  The upgrade should run to completion or a safe exit point as long as
  it takes less than about 900s (which is the timeout for sending kill).

  [Regression potential]
  Leftover processes might remain in the apt-daily-upgrade cgroup if the postinst scripts or some apt hooks do something funny.

  Shutdown might take longer due to the 900 second timeout.
