I cannot replicate this in Bionic, at least if I understand the steps to reproduce correctly. If this is still valid in Bionic, please re-write the description with clear steps to reproduce. Ideally, this should be something that could be recreated from a fresh install. Thanks!
** Changed in: gnome-system-tools (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-system-tools in Ubuntu. https://bugs.launchpad.net/bugs/685596 Title: users-admin doesn't report error when PolicyKit authentication fails Status in gnome-system-tools package in Ubuntu: Incomplete Bug description: Binary package hint: gnome-system-tools When I run users-admin (gnome-system-tools package version 2.32.0-0ubuntu1) in natty i386, clicking the "Add", "Delete", and "Advanced Settings" buttons has no effect. Clicking the "Manage Groups" button does bring up the "Groups settings" window. In the "Groups settings" window, the "Add" and "Delete" buttons have no effect. Clicking the "Properties" button does bring up the Group Properties window for the selected group. In the Group Properties window, changing the group ID to a number already in use by another group does issue an error, but changing the group ID number to a number not already in use or changing which users are members of the group fail silently (as though the operations had succeeded). When I run users-admin from a console, it prints this output to the command-line upon launch: GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications. (users-admin:1337): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed Clicking the "Manage Groups" button results in another assertion message being printed (every time it is clicked). Clicking other buttons mentioned above does not result in messages being printed. When I first experienced this bug, my system suffered from Bug 685349. I had thought that might have been the cause of this bug (though in hindsight I am not sure why I thought that). As a workaround for Bug 685349, I manually changed the value of the gconf2 key /apps/gksu /sudo-mode key from false to true. This fixed my problems elevating privileges to root in other applications, including other gnome- system-tools applications, but it did not appear to have any effect on the behavior of users-admin, including its output to the console. I bring this up to suggest that this bug in users-admin is occurring before any attempt is made to elevate privileges to root (or preventing such an attempt from being made). (This bug is the "situation" I referred to in Bug 685215 that had led me to try running users-admin as root.)
