[Bug 1670291] Re: Landscape: Upgrade 14.04.5 to 16.04.2 fails unable to reboot

[Damiön la Bagh]

Ok so this is still FUBAR but then on a higher level.


The upgrade failed miserably see the attached file. 
I was able to ssh into the machine after the upgrade.
ran dpkg --reconfigure -a as suggested see below

then I tried to reboot. which was a big mistake. 
when I try to reconnect to the remote machine

ssh: connect to host remotemachine port 22: No route to host

This is terrible. ssh should be like the first thing started always.
even grub should have some kind of ssh feature so if the grub menu shows
one could fix that remotely.

Now I have a unusable machine and have to go physically to the location
to try and reinstall everything by hand.

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
