Error: Problem: conflicting requests - nothing provides python3.7dist(defusedxml) = 0.5.0 needed by python3-saml-1.3.0-4.fc30.noarch https://github.com/onelogin/python3-saml/commit/064b7275fba1e5f39a9116ba1cdcc5d01fc34daa I've updated defusedxml recently, there is no API change so it didn't cross my mind that somebody would pin a specific version of it. This blocks the Python 3.8 rebuild of python-social-auth-core.
