Hello Richard Hughes!

Thank You for Your quick reply. I edited the file
/etc/dbus-1/system.d/org.freedesktop.PolicyKit.conf
as described and - voilà - the PackageKit works again.

Best regards,

Pär Johansson

Thank you!  That line added by the patch worked for me and I posted my problem/solution at Fedora Forums: http://forums.fedoraforum.org/showpost.php?p=1126554&postcount=98

I tried the recommended fix by adding the suggested line to

org.freedesktop.PackageKit.conf

Now if I choose System>Adminstration>Updates>Refresh

it still doesn't work, but I get a slightly different error message

failed to get a TID: Method "SetLocale" with signature "s" on interface "org.freedesktop.PackageKit.Transaction" doesn't exist
 (0)

Similarly if I try to  use Add/Remove Programs.

It may be that the automatic popup reminder works.

Someone should really try to find a comprehensive fix.

Might I also suggest that updates to PackageKit and related features be tested before being pushed out to the world?

When you break the ability for users to update, non-technical users are up the creek without a paddle.

Thank you Gandrara Ted, well said.  Darn it, now where did I leave my paddle? ;)

chill guys!!!

This fix truelly works

make sure Your org.freedesktop.PackageKit.conf
 looks like:

<!DOCTYPE busconfig PUBLIC
 "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>

  <!-- This configuration file specifies the required security policies
       for the PackageKit to work. -->

  <!-- Only user root can own the PackageKit service -->
  <policy user="root">
    <allow own="org.freedesktop.PackageKit"/>
  </policy>

 <!-- Allow anyone to call into the service - we'll reject callers using PolicyKit -->
  <policy context="default">
    <allow send_interface="org.freedesktop.PackageKit"/>
    <allow send_interface="org.freedesktop.PackageKit.Transaction"/>

  </policy>

</busconfig>

kde-menu > Administration > Update System Software Update Viewer
and everything works like a charm
