Comment 5 for bug 1605742

The Nova periodic stable mitaka test job installs paramiko==1.16.0

This is the upper-constraint since Nov 2015

This works fine.

The openstack-ansible project used paramiko>=1.16.0 and installed 2.0.1

openstack-ansible removed the requirement "paramiko>=1.6.0" later
    https://github.com/openstack/openstack-ansible/commit/b15363c#diff-b4ef698db8ca845e5845c4618278f29aL3
This however is only in openstack-ansible Newton and not in Mitaka:

Based on ^ I believe this is an issue of the openstack-ansible project which
doesn't cap the upper-constraint of paramiko in its stable/mitaka branch.
I don't see the need to backport anything to Nova's stable/mitaka branch.
I leave this as "incomplete" to get a second pair of eyes from auggy.
