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
