muon-updater/ PolicyKit: want to know password for updates

[Martin Bretschneider]

Hi,

if you get notifified by muon-updater in 12.04 (and at least in 11.10), 
the user has to enter his password in order to install (security) updates.

I guess that the user should *not* be asked for updates. He should only 
be asked if he wants to install or remove software. This is especially 
usefull for unexperienced computer users.

There is the package policykit-desktop-privileges for this purpose that 
has the following description:

-------------------------------------------------------------------
This package provides a set of PolicyKit privileges which allow 
Administrators
to run common actions without being asked for their password:

  * mounting and checking internal disk drives (through udisks)
  * setting the CPU speed and policy (through the GNOME CPU frequency 
applet)
  * setting the time and timezone (through the GNOME clock applet or through
    KDE)
  * Adding/changing system-wide NetworkManager connections
  * Update already installed software
  * Configure printers
----------------------------------------------------------------------

You see, the second to last says it. But it does not work here. It seems 
that the functionality of the package is in 
/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla 
with the following part:

---------------------------
[Update already installed software]
Identity=unix-group:admin;unix-group:sudo
Action=org.debian.apt.upgrade-packages
ResultActive=yes
----------------------------------------

My main user is member of the the group "admin" and since a week also 
"sudo".

But I am still asked for a password. Is this a kubuntu problem?

Do you know a solution. Is it a bug of the package 
policykit-desktop-privileges, polkit-kde-1 or muon-updater?

TIA and kind regards from Martin
