PROBLEM UPGRADING FROM FC2 TO FC6

[Albert E. Sten-Clanton]

Greetings!  I'm trying to upgrade from FC2 to FC6 using the CD images.  I used the images that the NCFTP DIR command tells me were created on 1 December.  I checked the downloaded images using sha1sum, checked each CD with sha1sum after burning it, and checked them all again via the process at the beginning of the installation.  They passed.  But after the thing checked dependencies and apparently began the install/upgrade, I got the following message:

Error
The file scim-m17n-0.2.0-6.fc6.i386.rpm cannot be opened.  This is due to a missing file or perhaps a corrupt package.  Please verify your installation images and that you have all the required media.
If you reboot, your system will be left in an inconsistent state that will likely require reinstallation.

I had the choice to retry or reboot.  I rebooted.  A quick check suggest that my old system's probably intact.

I'll be very grateful for any help with this.  After FINALLY seeming to have figured out how to burn good images consistently (using "disk at once" rather than cdrecord's default, "track at once"), I dared to hope this might be my great upgrade day.  Anyway, thanks!
