If you want you could first find out if you actually have any software from those archives installed on your system. I use the package "vrms", which can list these. If you do have contrib and/or non-free software installed, I would recommend to add "contrib" and/or "non-free" to keep them up-to-date. You should check if there are any files in /etc/apt/sources.list.d/, though, since those may also contain relevant configuration. Tobias
