Reading the installation guide for podman, they reference opensuse.org
as the official package repos for ubuntu:
https://podman.io/getting-started/installation
Using this repo allows us to pull in much newer version of podman on
ubuntu. The current PPA package repo hasn't been updated since late
2019.
