I installed Kubuntu LTS 12.04, and this bug affected me. I tried change configuration for Login Screen, and I was getting the permission error. It was solved only installing polkit-kde-1 package. This package should come in the default Kubuntu install, at least in the standalone install from CD/DVD. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to policykit-1-gnome in Ubuntu. https://bugs.launchpad.net/bugs/867737 Title: Kubuntu desktop missing dependency on polkit-kde-1 Status in “policykit-1-gnome” package in Ubuntu: Confirmed Status in “polkit-kde-1” package in Ubuntu: Confirmed Bug description: After installing KDE on regular Ubuntu using "apt-get install kubuntu- desktop", I am not able to change any of the system settings requiring administrative privileges due to the lack of the installation of "polkit-kde-1". It will fail with an error as described here below with Muon when I expected to be shown a dialogue to enter my password. Also other KDE software is affected. For example, when applying changes in Muon package manager, I get the error "This operation cannot continue since proper authorisation was not provided". Installing polkit-kde-1 solves this issue and a proper dialogue is opened to ask for the (sudo) password. Steps to reproduce (example): - Install regular Ubuntu - Install "kubuntu-desktop" using apt-get - During installation choose KDM as default login manager - Log in in the KDE desktop - Open (for example) System settings -> Login Screen. change Appearance, click the "Apply" button. Expected result: An authorization dialogue shown to enter my password, after which the changed would be applied. Actual result: Error dialogue: "This operation cannot continue since proper authorisation was not provided". None of the changes were applied. After manual installation of polkit-kde-1, logging out and logging back in, the result is as expected. My recommendation is to fix the dependencies/recommends of the KDE suite in Ubuntu in order to overcome this usability issue.
