I'm afraid that Free's suggestion hasn't worked for me yet. Probably because I'm new to all this. I have tried disabling the repositories that the application manager log says are causing a problem and nothing happens. The Internet Tablet School site has a good easy to understand section on what to do if the application catalogue is broken.

However I still can't get the problem sorted. The repositories that come up in the log the most are the Nokia ones which came installed ie Nokia catalogue (http://catalogue.tableteer.nokia.com/certified/ and Nokia Catalogue (3rd party software). I'm finding that I can install virtually no applications from the Nokia and Maemo site.

I'm wondering whether I could delete the entire catalogue and reinstall from www.gronmayer.com/it ?
