Bug description:
  https://github.com/systemd/systemd/pull/10061

  [Impact]

   * When logind is not available, shutdown command fails to schedule a
  shutdown, and despite its intentions to immediately shutdown, does not
  do so.

  [Test Case]

    sudo systemctl mask systemd-logind.service
    sudo systemctl stop systemd-logind.service
    shutdown +1

  The expectation is that system goes to shutdown.

  It is buggy if the system remains up - i.e. command returns to shell
  with exit code 1.

  [Regression Potential]

   * It is a corner case to run against systemd-shim logind / or logind
  not otherwise available. The function still performs a clean-shutdown,
  and should not cause loss of work.

  [Other Info]
   
   * Original bug report, running against systemd-shim/systemd-service post trusty->xenial upgrade, pre-reboot.

  
  Used Landscape (Paid Canonical Subscription) to upgrade one of my machines.

  Landscape only shows "In Progress" for more than 8 hours now and asked
  for a reboot of the machine in a second alert.

  In the reboot attempt I get the message:
  =========================
  Failed to set wall message, ignoring: Method "SetWallMessage" with signature "sb" on interface "org.freedesktop.login1.Manager" doesn't exist
  Failed to call ScheduleShutdown in logind, proceeding with immediate shutdown: Method "ScheduleShutdown" with signature "st" on interface "org.freedesktop.login1.Manager" doesn't exist
  =========================

  Steps to reproduce:
  * Fully updated 14.04.5 machine
  * Open Landscape
  * Choose the machine
  * Choose Packages
  * This computer can be upgraded to a newer release
  * Apply
  * Wait 2 hours
  * Alert comes in a seperate Landscape message Machine is ready for reboot
  * Choose Info... Power
  * Deliver to selected computers as soon as possible
  * Error message

  I found this thread on reddit about this issue maybe the solution can be built into the upgrade script
