Comment 3 for bug 1734353

I have the feeling, that the source of the issue has to do something with this patch, which was merged on 22nd Nov: https://review.openstack.org/#/c/519407/

In fact, if you check the logs from the 21st, the job fails for a different reason: https://logs.rdoproject.org/13/522013/1/openstack-check/gate-tripleo-ci-centos-7-containers-multinode-upgrades-pike/Za68238e87e4246ecb7f8850cc2674f29/undercloud/home/jenkins/failed_upgrade.log.txt.gz

While, the first job execution after the patch got merged (22/11 @ 06:53) starts failing because it can't find the docker puppet class: https://logs.rdoproject.org/01/521501/2/openstack-check/gate-tripleo-ci-centos-7-containers-multinode-upgrades-pike/Zd58d2a50ccdd425a86b2fd8bd31dafaa/undercloud/home/jenkins/failed_upgrade.log.txt.gz

When comparing both journal logs, we can see that one updates the packages, while the other doesn't:
