FC6

[pd520 york ac uk]

Hello,

I did try to upgrade a FC4 to FC6 but anaconda failed. I am uisng the 
Rescude CD and then the fedora6.iso The DVD has been checked. I can 
eventually access to the fc6.rpm files but anaconda fails. At one poin the 
/tmp/cdrom is mounted on /mnt/source but then the DVD is dismounted. 
anaconda complains on 
///mnt/source/Fedora/RPMS/firefox-1.5.7-7.fc6.i386.rpm, I guess that it is 
just because it is the first file to update.

What is wrong ?

Regards
