[Bug 2133012] Re: The "Restart Now" button in Software Updater does not restart the system

[Nathan Teodosio]

Hi Edoardo, thanks for the logs, Launchpad indeed does not let you
attach more than one at once so it is no problem sending various
attachments at you did as separate comments. An alternative is to send
it as attachments via e-mail to <2133012 at bugs.launchpad.net>.

As to the bug: I can see in the dbus log that RequestReboot is as
expected being sent by Update-Manager, and Gnome-Session is getting
ConfirmedReboot. So this is looking like a bug in Gnome-Session indeed.

Is there anything odd to your setup, in particular in the way you start
Gnome, or is it via the normal logi in screen (GDM)?

If you execute

  dbus-send --session --type=method_call /org/gnome/SessionManager
--dest=org.gnome.SessionManager org.gnome.SessionManager.RequestReboot

and accept the reboot prompt that appears, does the system reboot?

Title:
  The "Restart Now" button in Software Updater does not restart the
  system

Status in gnome-session package in Ubuntu:
  New
Status in gnome-shell package in Ubuntu:
  New
Status in update-manager package in Ubuntu:
  Invalid

Bug description:
  Every time the Software Updater application (from the update-manager
  package) has finished updating "core" packages like the kernel, it
  says that the computer needs to restart to finish installing updates.
  In that window, clicking on the "Restart Now" button brings up the
  restart pop-up ("The system will restart automatically in 60 seconds")
  but clicking on "Restart" on that pop-up does not do anything and the
  Software Updater application closes as if it just crashed. The system
  does not restart.

  The restart pop-up looks the same as the one brought up by the "Power
  Off" menu in GNOME when clicking on the "Restart..." option.

  When launching Software Updater with the Terminal (/usr/bin/update-
  manager --debug) it prints messages up until the message that says
  that the computer needs to restart shows up, but nothing from that
  moment on.
