Hi, For a regular Debian CD Rom, deleting the corresponding entry in /etc/apt/sources.list and adding it again using apt-cdrom should solve the problem of having it recognized. I don't know the details of the omsha CD's and how well they conform to the Debian format but quite probably it should work (suggestion: make a backup copy of sources.list, just in case it doesn't work :) Cheers, Eusebio ------
