When I do this, I get a lot of errors about missing python-* packages. I know that rencently, the python-* dependencies were changed to a prefix of pgadmin4-python. This all worked fine until the python-* packages were removed from the yum repository. When that happened, the currently-posted pgadmin4 is based on a specfile that still has Requires lines referencing the old dependency package structure, that are now missing.
This specfile still has a bunch of Requires lines for
Requires: python3-babel >= 1.3
Requires: python3-flask >= 0.11.1
etc.
I know there's a FIXME written to do the work, but if that is going to take some time to do, I might request that the python-* packages be restored temporarily so that the current version of pgadmin4 on the yum repository will be able to install properly.
