KDE 4.7 - KPackageKit - "Failed to obtain authentication" due to missing "polkit-kde-1" dependency

[theghost]

Updating 11.04 to KDE 4.7 resulted in problems with kpackagekit.
Update went fine but since update i can't install updates with kpackagekit.

It seems "kubuntu-desktop" does not require "polkit-kde-1" as dependency.

Description - Steps to reproduce:

1. Install Ubuntu
2. Add Kubuntu Backports PPA for KDE 4.7
3. Install "kubuntu-desktop" metapackage.
4. Start Kpackagekit and search for updates
6. Updates are found
7. Try to install updates via KPackagekit results in error: "Failed to obtain authentication"

Solution:

1. Install "polkit-kde-1"
2. Retry update installation via kpackagekit
3. Everything works fine

Edit - It seems it was also a bug before KDE 4.7:

- There is an upstream bug, reported by an kubuntu 11.04 user too: https://bugs.kde.org/show_bug.cgi?id=274204
- There is also a duplicate bug on launchpad for 11.04: https://bugs.launchpad.net/ubuntu/+source/kpackagekit/+bug/758592
