I found one more source of this bug (It was pointed by Marsikus at habrahabr.ru): https://github.com/openstack/oslo.config/compare/3.18.0...master
As you can see, oslo.config have dependency for python-rfc3986== 0.2.0 in version 3.18.0, and 0.2.2 in stable/newton.
And https://releases.openstack.org/newton/index.html#oslo-config says that 'Newton' is 3.17.0.
I think it is a maintenance mistake from oslo.config upstream.
