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

[Edoardo La Greca]

Hi Nathan, thanks for your replies. I'm reassured to know that it's not
wrong to make multiple comments for multiple attachments.

I can confirm that there is nothing odd to my setup. I never modified
any setting regarding GDM or the way Gnome starts, as far as I can
remember. As a matter of fact, this happens both on my desktop and
laptop PCs, both of which run the same Ubuntu release and have Gnome
session-related stuff left untouched since installation.

I also confirm that the dbus-send command you wrote indeed reboots the
system, once the prompt button is clicked.

Unfortunately the Launchpad website flagged the dbus-monitor output file
(dbus.log) as an HTML document when I uploaded it (due to its syntax,
probably) but the newlines are still there. If you download the file and
view it with a local text editor you should see it formatted correctly.

As you requested in the second comment, I also re-run dbus-send while
also keeping the dbus-monitor command in background (dbus-monitor ... &
dbus-send ...).

Output of dpkg below:

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.
