I can not update the pre installed repositories!

I have no problems with:
Maemo Extras, Maemo Extras Testing and Mozilla Catalog

but the preinstalled:
Nokia Programs, Nokia system-softwareopdates and Ovi (The names of the repositories are translated from Danish don't know the English names for them)
are not able to update.

I think the problem started when I added the Maemo Extras Testing repository.

Can anyone help me fix this problem?
