Public bug reported:

Binary package hint: yelp

My machine (amd64) was running fine under jaunty (amd64) until
yesterday, when I upgraded to Karmic. Things seem to run well, except
for (at least) a devkit/policykit problem.

When I plug a USB memory stick, a window shows up telling me that the
volume cannot be mounted because I'm "Not authorized". This stick could
be mounted OK on the jaunty 64 before, and can be mounted OK on another
machine (amd64) on which I installed karmic from scratch yesterday. So
I'd say it's an upgrade problem. But I cannot manage to determine where
the permissions are managed.

I tried "devkit-disks --mount ..." by hand and, effectively, it tells me:
shell>devkit-disks --mount /dev/sdc1
Mount failed: Not Authorized

I don't see any big difference with my working other karmic machine. In
particular, I belong to the same /etc/group groups.

However, when trying:
shell> polkit-auth --show-obtainable
on the failing machine, the output is empty.
If I run the same on the working karmic, I get 4 lines:
org.freedesktop.policykit.read
org.freedesktop.policykit.revoke
org.freedesktop.policykit.grant
org.freedesktop.policykit.modify-defaults
Comparing the strace outputs from both machines didn't show me any conclusive 
differences.

Another problem which might (not ?) be related: when I try "users-
admin", the small key icon at the bottom tells me that I am "Not
authorized to make changes". It happens that this is working as expected
on the other karmic64 machine.

I also noticed another problem, which might (not ?) be related: when I
try to suspend the machine (user menu / suspend), all it does is fire up
the screen saver. Likewise, when trying "restart" or "shutdown", all it
does is log me out and bring me to the gdm screen. I suspect another
authorization problem which forbids me to perform system-wide actions.
It happens that all this is working as expected on the other karmic64
machine.
