We got two similar release processing failures: > - tag-releases https://zuul.opendev.org/t/openstack/build/707bb50b4bf645f8903d8ca59b43abbf : FAILURE in 2m 31s This one was an error running the tag-releases post-merge job after https://review.opendev.org/c/openstack/releases/+/779217 merged. It failed with: Running: git push --dry-run ssh://release@review.openstack.org:29418/openstack/tripleo-ipsec.git --all ssh://release@review.openstack.org:29418/openstack/tripleo-ipsec.git did not work. Description: Host key verification failed. > - tag-releases https://zuul.opendev.org/t/openstack/build/655e8980a53c4e829de25f0b8507b5f6 : FAILURE in 2m 57s Similar failure while running the tag-releases post-merge job after https://review.opendev.org/c/openstack/releases/+/779218 merged. Since this "host key verification failed" error hit tripleo-ipsec three times in a row, I suspect we have something stuck (or we always hit the same cache/worker). -- Thierry Carrez (ttx)
