Did you install kdesudo or kdesudo-kde3?

On closer inspection, it seems that the feature you are trying to use is a Kubuntu-specific feature, requiring this package that has not been rebuilt for Ubuntu Intrepid or later: http://packages.ubuntu.com/hardy/language-selector-qt I am seriously considering removing the buttons labeled "Install New Language", "Uninstall Language", and "Select System Language" from the official Trinity distribution. These buttons can be added later via a patch for Kubuntu-specific builds, after the package mentioned above has been successfully built under Maverick. As such I request that you open a bug at http://bugs.pearsoncomputing.net as a feature request for the language selector buttons under Kubuntu. Thanks! Tim

<snip> Yes it is. For a while the downstream mirror was out of sync with the local master due to a configuration problem on the mirror end of things. The problem has since been resolved, and a simple "apt-get update" (without the quotes) should resolve the problem you are seeing. Tim
