You haven't got any! What distro have you installed and how? It rather looks as though you have got Ubuntu of some sort or other, but how did you install it? I have never come across a Ubuntu installation (nor indeed any other) that was installed with _no_ repositories. Dr. Klepp is right, if you have Ubuntu with GNOME you can set repositories up in Synaptic quite simply. In fact, there may be a simple way anyway. Could you post the whole of your sources.list, including the lines commented out? Lisi
