ansible failing to install PHP from lamp server playbook

I am going through the ansible for devops book and getting stuck on chapter 4.
When I run the ansible playbook for the lamp server, it gets stuck at the task "Add ondrej repository for later versions of PHP" with the following error:

FAILED! => {" changed": false, "msg": "Failed to update apt cache: W: Updating from such a repository can't be done securely, and is therefore disabled by default., See apt-secure(8) manpage for repository creation and user configuration details., The repository xia Release' does not have a Release file."}

I have tried adding more time to give the process to end gracefully. I have tried changing the vagrant box. These did not help.
and I am not sure where to go from here. I am guessing the source either does not have the release files anymore or some process is hogging all the resources making it impossible to run this command from ansible playbook.
