Thanks a much for this blog. But may I know on which Ubuntu version this works? I tried on Ubuntu 20.04 and Ubuntu 16.04 but it failing with below errors:
ON Ubuntu 16.04:
After podman installation, podman cli throws below error.
root@c9442a8f1499:/# podman ps
ERRO[0000] 'overlay' is not supported over overlayfs
Error: error creating libpod runtime: 'overlay' is not supported over overlayfs: backing file system is unsupported for this graph driver
Err:5 ppa.launchpad.net/projectatomic/pp... focal Release

E: The repository 'ppa.launchpad.net/projectatomic/pp... focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

It probably does not work in the first version, and not supported yet in the newest version. It's probably better if you check out the updated instructions, shown in the next comment.
