Restart/Shutdown functionality broken. Logout is perfomed instead.

Restart/Shutdown functionality broken. (Any desktop manager)
Only logout is perfomed instead.

The following work as expected:
sudo init 6
sudo init 0
sudo shutdown -P now
sudo shutdown -r now

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem. Fresh Install of Ubuntu 12.10 64bits. I can only reboot and shutdown by command line.

[misteraph (laporte-raphael)]

I found a workaround here.

https://www.grendelman.net/wp/policykit-adventures/

Create a file /etc/polkit-1/localauthority/50-local.d/usershutdown.pkla

Put his text inside and reboot

[Allow Shutdown]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.stop-multiple-users
ResultAny=yes
ResultInactive=yes
ResultActive=yes

[Allow Restart]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.restart-multiple-users
ResultAny=yes
ResultInactive=yes
ResultActive=yes

However, I don't known if it is a clean method.

It seems that policykit gets screwed up again on Ubuntu upgrades and installs. This is a recurring issue. All versions to my experience have had issues with screwed up policykit.

I found this in /var/log/syslog
