Originally my surces.list file (for apt) pointed to my cd rom drive, which had potato cd #1 in it. Since then I've changed sources.list to get stuff from the net, but how do I add the cd drive back to sources.list? I suspect it's something like file:/cdrom but I've tried that and no luck... (yes, I know now I could use dpkg -i directly, but I want to be able to use apt-cache search and apt-get for easyness.) thanks alex
