Failed to download repository information due to missing CDROM

I have been using Ubuntu for about 6 months now without any problems until I ran the update manager yesterday and kept getting this message:

 Failed to download repository information Check your Internet connection

Then in the more details box it reported:

W:Failed to fetch cdrom://Ubuntu 12.04 LTS _Precise Pangolin_ - Release amd64 (20120425)/dists/precise/main/binary-i386/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
W:Failed to fetch cdrom://Ubuntu 12.04 LTS _Precise Pangolin_ - Release amd64 (20120425)/dists/precise/restricted/binary-i386/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
E:Some index files failed to download. They have been ignored, or old ones used instead.

I have tried using the terminal commands given but have had no luck.

The update manager is looking for packages on the Ubuntu CD/DVD. If it is not inserted you get that error. You can disable the CD as package source. Open the software center, go to Edit/Software Sources... and disable the CD on the first tab.
