If you are using the same CD to install more packages ad the one you installed the OS with then the lines in /etc/apt/sources.list already exist, just uncomment them and the CD will be read.

If the system has Web access then these probably won't be used as the versions of the packages online will undoubtedly be newer than the ones on the disk.

Can you help with this problem?
