I think you are completely confused. I said "Stable CSSU" testing, devel and thumb are completely different. You should only have catalogues:- Nokia SSU Maemo.org Extras and Community SSU* (See below) Any other repository is not recommended if you don't understand. Also the mirrors are no longer required. CSSU Features is a separate package that allows you to change the settings of CSSU without Terminal. Having "CSSU Features" doesn't mean you have CSSU. The only way to install CSSU is via:- http://repository.maemo.org/communit...mantle.install * Clicking on the above link with your device will install the Community SSU repository. If you want to start again (recommended) see the following guide. http://wiki.maemo.org/N900_The_Perfect_Setup
