[K12OSN] V-4.2.0 Problem installing

[Richard Johnson]

I keep running into a problem loading the 4.2.0. On disk 2 the package 
'xorg-x11-6.8.1-12.FC3.21 cannot be opened...". I downloaded Disc2 again 
and burned it (2 times) and still stops. Is anyone else having this 
problem? Or, any suggestions?

Thanks,
