When I update my computer, I get the following:
cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/main/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/multiverse/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/restricted/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/universe/binary-amd64/Packages Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/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 cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/multiverse/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 cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/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 cdrom:[Kubuntu 13.04 _Raring Ringtail_ - Release amd64 (20130424)]/dists/raring/universe/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
