APT: Failed to fetch cdrom://[Debian...

[Marko Ranđelović <markoran@eunet.rs>]

I use Wheezy and I use DVD 1 in APT and http as well. DVD *is* working, but whenever I do 'apt-get update', I get and error:

E: Some index files failed to download. They have been ignored, or old ones used instead.

It's disturbing and it's the only way I want to eliminate this error messages.

Kind regards
