Since yesterday, I've been consistently getting an error when trying to refresh the "Nokia certified" repository. The error as displayed in the Application manager is:

Nokia certified
http://catalogue.tableteer.nokia.com...l/Packages.bz2
MD5Sum mismatch

The error has persisted through different networks and after deleting that repository and selecting it again via the gronmayer.com site.

I'm primarily a Irix/Sun/Redhat admin, so I'm not afraid of using the command line to fix the problem (if it's an issue with cached data on the tablet), but I'm really not familiar with debian and apt, so I could use some direction.

Thanks
