Title:
  Running 'unattended-upgrades --dry-run' reboots the machine

Status in “unattended-upgrades” package in Ubuntu:
  Triaged

Bug description:
  Much to my surprise, when I did a dry-run test of unattended-upgrades
  my server was forcibly rebooted. I must have had the file '/var/run
  /reboot-required' present.

  But needless to say: a --dry-run should NOT perform a reboot of the
  server with zero warning. Seriously.

  Output from /var/log/unattended-upgrades.log

  Version: 0.76ubuntu1

  As an aside, it makes a lot of sense to me to put the reboot on a
  timer, even if it's only a one minute (i.e. shutdown -r 1). That would
  have at least given me a chance to prevent the reboot if I had seen
  the warning. If that's a configuration setting I don't see it
  anywhere.
