+Subject: [PATCH] Use dnspython package on Python 3
+
+The dnspython3 package is obsolete and superseded by dnspython. The dnspython
+package supports Python 2 and Python 3.
+
+The change also fixes a problem with Fedora 30's new Python dependency
+generator. The python3-dnspython package does not provide dnspython3
+distribution:
+
+nothing provides python3.7dist(dnspython3) needed by python3-kdcproxy-0.4-4.fc30.noarch
+
+See: https://pypi.org/project/dnspython3/
