No elevated permissions password prompts appearing

[fallen-luciel]

Hi all,

This is an, almost fresh install of Xubuntu. The problem I'm having is, whenever I do something through the Gui that asks for my sudo password (install something, uninstall something, attempt to change a setting, etc) the prompt that normally should appear where I would write my password, doesn't. Meaning I literally can't do anything that requires elevated permissions on the gui, I need to go to the CLI to do it.

Example,
- Click on the menu button
- Click on software
- Click on Installed
- Click on any piece of software you no longer want.
- Click on Remove

Normal behaviour would be, you now get the password prompt. I don't, so clicking on Remove does nothing.

Thanks for any help or ideas in advance!

(PS: I've tried creating other users, in case it was an issue with the profile to no avail, same issue).

No clue if this matters or not, but is the problem userid in the adm or sudo groups?
id will let you check that.

Hi TheFu,

It is

"uid=1000(username) gid=1000(username) groups=1000(username),4(adm),24(cdrom),27(sudo),30 (dip),46(plugdev),118(lpadmin),126(sambashare)"

What happens when you run pkexec from a terminal:

pkexec echo

Hi Sisco311,


What happens when you run pkexec from a terminal:

pkexec echo

This:


==== AUTHENTICATING FOR org.freedesktop.policykit.exec ===
Authentication is needed to run `/bin/echo' as the super user
Authenticating as: RSO Systems Administrator,,, (rso-sysadmin)
Password:

After the password is introduced:


polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Faile d: No session for cookie
==== AUTHENTICATION FAILED ===
Error executing command as another user: Not authorized

This incident has been reported.

Running it with sudo, nothing happens aside from it asking for the password on the terminal.

Make sure that policykit-1-gnome is installed and PolicyKit Authentication Agent (/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1) is added to the startup applications.

Good morning,


Make sure that policykit-1-gnome is installed and PolicyKit Authentication Agent (/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1) is added to the startup applications.

policykit-1-gnome is installed and added to startup applications, still no joy unfortunately.

Check if the auth agent and the daemon is running:

ps -ef | grep polkit

systemctl status polkit.service


If the agent is not running, try to start it manually an see if it produces any error message:

/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
