Currently, this is broken upstream and waiting on a fix

This has also become an issue with the CentOS6 Vagrantfile (see: https://ci.adoptopenjdk.net/job/VagrantPlaybookCheck/OS=CentOS6,label=vagrant/957/console)
In the provisioning stage, it's not able to install libselinux-python , causing the Update /etc/hosts file - IP FQDN hostname task to fail.

Well, This may or may not have been known but CentOS6 is at the end of it's life (https://wiki.crowncloud.net/index.php?fixing_update_issues_in_centos6), so, naturally, all the yum stuff becomes broken.

As Stewart attempted in the above referenced PR, we can switch to using vault.centos , and I've managed to get this working with the CentOS6 Vagrant VM.

This is still an issue, unfortunately - the CentOS SCL repo (installed here , also has an out of date baseurl, so I'm looking to create a task that will change the repo to using CentOS Vault like the changes made to the Vagrantfile and Dockerfile in #1765 .
