I found the following BZ ticket which explains this situation...

https://bugzilla.redhat.com/show_bug.cgi?id=1634658

FreeCAD chose to use PySide over PyQt so this (and a couple of other packages) are preventing me from switching it over to Qt5.

Is there anyone interested in getting PySide2 in Fedora and willing to submit a Review Request? I'll volunteer to be the reviewer..

Thanks,
Richard
