We haven't used tripleo-incubator in some time and it is no longer maintained. We are planning on officially retiring it ASAP[0]. We had previously said we would do it for the pike py35 goals[1] but we never got around to removing it. Efforts have begun to officially retire it. Please let us know if there are any issues. Thanks, -Alex [0] https://review.openstack.org/#/q/topic:bug/1768590+(status:open+OR+status:merged) [1] http://git.openstack.org/cgit/openstack/governance/tree/goals/pike/python35.rst#n868
