Change https://review.opendev.org/#/c/608636 removes apt-cacher-ng, but fails to correctly and completely remove references to it in the hosts and containers OSA manages. Specifically, with regard to the changes to the Yum package manager proxy in playbooks/common-tasks/package-cache-proxy.yml:
- The "line" argument to lineinfile specifies a line in which the proxy URL is surrounded by double quotes, but the previous code did not produce a quoted line, so this pattern doesn't match and the proxy line in /etc/yum.conf is not removed.
- The /etc/yum.repos.d/percona-original-release.repo file also specifies the proxy line, but there's no task to remove it.
The result is that during an upgrade to Rocky on a Yum-using infrastructure, the upgrade process fails at the Galera upgrade step. Upsettingly, it only fails after the first Galera node has already had its Galera package uninstalled, leaving the cluster in a non-optimal state, and causing further runs of the play to fail differently because Galera is no longer available to verify the cluster status on the node.
