Comment 1 for bug 1890922

Indeed, Ubuntu Bionic does not seem to meet the requirements: https://opendev.org/openstack/requirements/src/commit/7ea3fea5458a8e3ef4e03ba15ea64b2ff16dfcf1/upper-constraints.txt#L184

However, this is not a Kolla issue as binary builds simply ensure compatibility with distributions and this distribution delivers this version.

If Ubuntu ever provided a newer version, we would pick it up.
