Repositorio desde CD-ROM / imagen .iso

[JOSE LUIS PALACIOS VERGARA]

Estimados Listeros:
Necesito por favor si alguien sabe la manera correcta de que una imagen de
imagen de un DVD de Debian quede correctamente accesible desde el
repositorio local.
La imagen la tengo en:

/mnt/debian-6.0.6-amd64-DVD-1.iso
la unidad quedó montada en:
/media/cdrom0
mount -o loop /mnt/debian-6.0.6-amd64-DVD-1.iso  /media/cdrom0

Luego hago

apt-cdrom -d=/mnt/cdrom add
Using CD-ROM mount point /media/cdrom/

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

Con lo que no puedo utilizarlo para instalar nada desde esa unidad.
Alguien tiene idea de cual puede ser el problema.

Muchas Gracias
Feliz 18!!!
