Problems installing kernel-source with Mdk 10.1 Community

Hi.

In my Mdk 10.1 Community, when I tried to install the kernel-source
with the command '# urpmi kernel-source', first I got the message

unable to read rpm file [/mnt/cdrom/media/main2/kernel-source-2.6-2.6.8.1-10mdk.i586.rpm]
from medium "Installation CD2 (x86) (cdrom2)"

, and then in the end the message:

Installation failed, some files are missing:
/mnt/cdrom/media/main2/kernel-source-2.6-2.6.8.1-10mdk.i586.rpm
You may want to update your urpmi database

. What's that? What to do?

Thanks,
Rodolfo

Your installed Linux is reporting problems with the index files that were loaded from the disks, which tell it the contents of the CD's RPM files.

urpmi.removemedia "Installation CD2 (x86) (cdrom2)"

Along with all the others...
