Not sure how to proceed on that. When yum get's stuck like that,
it does not give any technical details on why it is stuck trying to
resolve the conflict. Even the -v flag (which I have not tried yet)
might not reveal the underlying cause of the hang), but I will try
it.

None! No dups at all.

Yes. No duplicates at all - but how would that help in understanding the
cause of the hang?

I do not mean to draw any fire here, so please withhold you ire  :) :)
Just my $.02's worth of some thoughts ....

So far it seems to me that yum and dnf's internal operations,
being run by interpreted languages with many modules, it makes it
difficult, to say the least, to run a trace, such that one can see where
the failures occur (in what function, with what args), and where the
hangs occur, and what the values of the args are at the hang or failure 
points.
This is why I think binaries that are not stripped and not compiled with any
optimization, are ideal for implementing within them verbose debugging,
especially at critical points, within the source code.

Such debugging is ideal, but I understand, not always practical.
