I have a kind o Kubuntu-Studio 9.10

I installed from Ubuntu Karmic minimal, so i did install KDE.

i have update-manager-kde, update-notifier-kde and kpackage kit installed. for manual installing i use synaptic though.

in the repositry-manager the automatic updates are anabled (daily).

but it is not checking for updates. i checked manually in synaptic, and there are updates available.

so, how do i let it check automaticly for updates?
