Great, then i'll download cssu stable for now. However, when I got to download "Backupmenu" from the applications manager a message is appearing that says : "APPLICATION LIST PARTIALLY REFRESHED.SOME CATALOGUES UNAVAILABLE.CHECK CATALOGUE DETAILS" And when I go to check catalogue details the failed catalogues are : Maemo extras-devel, Mozilla multi beta catalog, and Mozilla multi catalog. So, backupmenu is not appearing in the list to download. On the other hand, when I go to "faster application manager", backupmenu is present , but when I try to download it the following message appears : "Some of your packages have unmet dependencies which could not be fixed". So, by this I can't download backupmenu and so many applications. Have any idea what is going wrong?
