I believe this is the source of your problem.  In older days, yum used
header files in repodata.  Nowadays, yum uses byte-ranges to download
just the header of each RPM to compute the dependencies.

Yum cannot use only the data in repodata to tell you which RPMs are
required.  It has to download a byte-range of the RPM you are trying to
install (the header), so it can read the deps.
