I'm using ubuntu 9.10 and when i check for update, it gives me an error message:

Failed to fetch cdrom://Ubuntu 9.10 _Karmic Koala_ - Release i386 (20091028.5)/dists/karmic/main/binary-i386/Packages.gz  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

Some index files failed to download, they have been ignored, or old ones used instead.

What to do?
Thanks in advance.

It looks as though the computer is looking for the CD as a repository. You need to edit your sources list to make this inneffective.

Open a Terminal and input the command: gksudo gedit /etc/apt/sources.list

Look for references to the CD being a repository - probably at the top. Put a # at the begionning of the lines you want to be inneffective. Save and exit Gedit. Try again.

Or go to System > Administration > Software Sources, and untick the CD in the white box at the bottom of the window.
