I have an N800 that has the latest firmware updated, and when I add the Bora repository:

Web address: [WWW] http://repository.maemo.org/
Distribution: bora
Components: free non-free

and then reload the catalog in the application manager, it says it cannot refresh the list, using the last list. However it looks like it read the repository as I was trying to add osso-xterm and it was there after adding this repository. If I disable that repository the message doesn't come up. Maybe it is one of the components (maybe non-free)? Thoughts?
