Stop Ubuntu’s Request for Installation CD

Because Ubuntu keeps the CD as an installation option (by default), it sometimes asks for it when installing software and such. Lifehacker recently listed instructions (derived from FOSSwire) on how to disable this annoyance.

1) In Ubuntu (the normal Gnome version), go to:

     System > Administration > Software Sources

2) In Kubuntu, head to the Adept Manager application, then go to:

     Adept > Manage Repositories

3) In Xubuntu, hit the Applications button on the top panel, then go to:

     System > Software Sources

4) Go to the Third Party Software tab.

     In Ubuntu 7.10, this option is in the “Ubuntu Software” tab.

5) Uncheck any entries starting with “cdrom,” then reload software lists if prompted.
