The SAS Viya 3.5 site.yml and update-only.yml playbooks might stall during the "Execute Configure vault" task when using Ansible core versions 2.15.0 through 2.15.3.

You can identify whether the task is running via the following message in the console or the deployment.log:

2024-04-08 17:37:28,838 p=19567 u=cloud-user n=ansible | TASK [vault-x64_redhat_linux_6-yum : Execute Configure vault] ***********************

This task generally completes in less than one minute, and this output is no longer visible in the console or at the bottom of the log. 

If this task produces no output after several minutes, run the following command on the Ansible controller machine to check the Ansible version:

ansible --version

If the output shows that your Ansible core version is 2.15.0 through 2.15.3, complete the following steps to upgrade the Ansible core version:

1. Use Ctrl+C to exit the playbook execution.
2. Upgrade Ansible core to 2.15.4 or later. Refer to MAXIMUM_RECOMMENDED_ANSIBLE_VERSION in your sas_viya_playbook/vars.yml file for the version that you should not exceed.
3. Re-execute the playbook.
