unresolveable updates message

[Jude DaShiell <jdashiel@xxxxxxxxxxxxxx>]

I have fedora core 2 mostly installed and this is the speakup version of 
the product needed because I need a screen reader to use a computer under 
any circumstances.  I ran up2date and got a chain of three programs that 
are an unresolveable update one of which is expect another python and I 
don't remember what the third program is now.  What short of reinstalling 
the system can be done to clear this kind of problem?  disc3 and disc4 of 
the fedora core 2 set have never burned successfully and that was even 
after rsync.  I could reinstall fedora core 1, those discs all burned 
successfully but I need to know then how to use either yum preferably or 
up2date to upgrade the whole system back to fedora core 2.  I'm wondering 
in future if the rpm data bases could be updated with a field like 
temp_gone which would be true/false and when one of these unresolveable 
chain situations comes up again, first mark in the data base all records 
temp_gone=true that is needed to to resolve the dependency, then download 
the files that couldn't be downloaded and mark them as temp_gone=true as 
they're downloaded, then change all temp_gone=true to temp_gone=false in 
the data base.  Any help solving this immediate problem will be much 
appreciated.
