I'm having a problem updating my system. Every time I try it comes out with:
"Failed to download repository information. Check your Internet connection."
I am connected to the internet I can browse the web perfectly fine.

The description in the error message is thus:
W:Failed to fetch cdrom://Ubuntu 10.10 _Maverick Meerkat_ - Release i386 (20101007)/dists/maverick/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 10.10 _Maverick Meerkat_ - Release i386 (20101007)/dists/maverick/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.

im at a loss what to do any help would be appreciated. XD
