Description Joseph Nahmias 2019-07-02 13:29:34 UTC

User-Agent:       Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Build Identifier: 

I have a new RHEL 7.6 server which I have configured with the epel repo. I have set up Xrdp and xfce on this server.  Now, when I connect via RDP, the desktop launches properly; however, xfce-polkit always just gives a blank error dialog.

When I run it from a terminal window, this is what I get:

$ /usr/libexec/xfce-polkit

** (xfce-polkit:2512): CRITICAL **: 09:20:52.415: polkit_agent_listener_register_with_options: assertion 'POLKIT_IS_SUBJECT (subject)' failed

(xfce-polkit:2512): GLib-GObject-CRITICAL **: 09:20:55.982: g_object_unref: assertion 'G_IS_OBJECT (object)' failed


Reproducible: Always

Steps to Reproduce:
1. Log in to the system
or
2. Run /usr/libexec/xfce-polkit


Actual Results:  
Error.

Expected Results:  
No Errors.

Hello,

since xfce-polkit is really not a part of RHEL shipped and is not maintained by Polkit Devel team, I cannot guarantee you a correct answer.
Try to find out if another polkit agent isn't running, e.g. polkit-gnome. If yes, kill them all, then try again. If that doesn't help, try uninstalling them (polkit-gnome, polkit-kde, polkit-qt etc.) and reinstalling xfce-polkit, as there can be only one agent initiated by the session manager (also binaries in /usr/libexec are not supposed to be run by users)

Anyway moving this BZ to responsible maintainer.

Thank you.
Jan Rybar

I don't see any other agents running, just polkitd.

$ ps -ef | grep [p]olkit
polkitd  14438     1  0 Jul01 ?        00:00:02 /usr/lib/polkit-1/polkitd --no-debug

Bump.  Any advice on this issue?

Comment 5 Kevin Fenzi 2019-07-17 22:18:31 UTC

I'm afraid not. Does it work as expected if you login directly to the console? Or is this a headless machine?

Do we support this kind of combination? My assumption is xfce4-polkit is not of much usefulness without the other Xfce elements. Please try to install a full Xfce desktop and reproduce.
