reproduced with puddle 2017-01-18.5
reproduced with puddle 2017-01-19.2 It seems to come from the version of python-ryu since [1] that requires ryu 4.7 # rpm -qa python-ryu python-ryu-4.3-2.el7ost.noarch Additionaly neutron updates the requirements on this lib 1 month ago and now it requires ryu >= 4.9 [2] [1] https://github.com/openstack/neutron/commit/92199dbd83a1a5a9c02cb2d9e2651d3f285b611e [2] https://github.com/openstack/neutron/blob/master/requirements.txt#L22
