keeps asking for the CD how do I force it to stop asking for the CD

Question

I have installed 12.04 and am attempting to update the wireless drivers (I have a Dell Insiron 6400), but it keeps asking for an installation CD that I do not have. How do I force it to stop asking for the CD and go to the network? The commands I am running are:

~$ sudo apt-get update
~$ sudo apt-get install firmware-b43-installer
~$ sudo apt-get remove bcmwl-kernel-source
~$ sudo reboot

It asks for the Cd at step 2

Answer 1

You can sudo nano /etc/apt/sources.list and comment out the CD-ROM lines near the top of the file by placing a # symbol as the first character. Or you can launch the software center and edit > software sources and uncheck the cdrom as an option.
