Why Use PPA for Ansible Installation?
The PPA (Personal Package Archive) offers the latest stable versions of software, which may not always be available in the official Ubuntu repositories. The PPA is maintained by trusted developers and is often the quickest way to access updated software. Using the Ansible PPA, you can ensure that you’re running the most up-to-date and secure version of Ansible on your system.
