Bug#942234: gdm3: the button «Shutdown» does not work anymore

[Jean-Marc]

Package: gdm3
Version: 3.34.0-2
Severity: normal

Dear Maintainer,

Since the last upgrade to GDM 3.34, the shutdown button does not work anymore.

If I click on it, I get the popup window with the three buttons (Cancel, Reboot, Shutdown) but clicking on Reboot or Shutdown just close this popup window and does nothing more.

Looking in /var/log/daemon.log, I found this message each time I use the GDM Shutdown option:
Oct 12 20:43:19 machineName gnome-session-binary[11980]: WARNING: Shutdown failed: GDBus.Error:org.freedesktop.DBus.Error.InteractiveAuthorizationRequired: Interactive authentication required.

Moreover, I also notice this in the systemctl status gdm.service output:

Maybe something missing since the last upgrade from 3.30.

Maybe it is because of the file /etc/securetty.

It was in the package login since Buster but it is not present in this package in Bullseye anymore.

Regards,

Jean-Marc
