@Brian Murray I can't find this package on my system. If anything didn't get wrong I only install kde-standard to install KDE, even kubuntu-* is not installed.
Currently I found that only if Update Manager found no update will display this message. If there is update not applied Update Manager will not show distribution upgrade information. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1174533 Title: Update Manager shows Kubuntu 13.04 available, but the system is actually pure Ubuntu running KDE | [zh_TW]更新管理員在純種 Ubuntu ,跑 KDE 的系統上顯示有 Kubuntu 13.04 可以升級(?)
