please insert the disc labeled ‘Ubuntu 7.10 _Gutsy Gibbon’” error

Media change: please insert the disc labeled ‘Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20770716)

I was trying to install VMWare Server on Ubuntu Gutsy Gibbon (7.10) yesterday and I came across this error:

Media change: please insert the disc labeled 'Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20071016)

The fix for this one was easy. I found the answer in the Ubuntu Forums. The details are summarized below.

-You have to comment out the “CDROM” line in your “/etc/apt/sources.list” by typing the following at the Terminal:
gksudo gedit /etc/apt/sources.list

-Once you have your /etc/apt/sources.list file open look for the following line:
deb cdrom:[Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20071016)]/ gutsy main restricted

-Comment the line out so that it looks like the following line:
#deb cdrom:[Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20071016)]/ gutsy main restricted

-Save the “/etc/apt/sources.list” file and close it.

-Update your “/etc/apt/sources.list” by typing the following at the Terminal:
sudo apt-get update

That’s it! You should be able to do “apt-get” now without getting the Media Change error. Happy Installing!
