We're encountering a bug in TripleO, see https://bugs.launchpad.net/tripleo/+bug/1856864
In the meantime please do not recheck or approve a patch, the gate is already fully loaded; we'll purge it, fix the bug and recheck what needs to be done.
You can follow the progress of that work on our IRC channel #tripleo.

Thanks for your patience.
