I do not believe that updating via the distro DVD images is implemented any  
more. You must use fedup to update.

You are assuming that you will be able to boot at all, after skipping the  
damaged package.

If the damaged package is glibc, or one of the critical gnome, systemd, or  
kernel packages, don't expect to be able to boot the resulting brick.

Also, you do not know whether the remaining 88% of your DVD is any good at  

Besides, this is probably a moot point, since updating must be done via  

If you do happen to have a DVD image, you could skip downloading a bunch of  
stuff by using fedup --iso. But you don't need to actually burn the ISO  
image, for that, and, in fact, fedup does not support CD/DVD based updates  
(as I was amusingly informed on one of my machines by fedup, which was very  
convinced that my /home mount, with the DVD image, was a physical DVD drive).
