Hi, and thanks for opening a bug report here.

Can you please include the result of the following podman commands?

podman version
podman info -f 'json'
podman images
podman run hello-world

We support Ubuntu, but do not explicitly support Pop!OS (which is based on Ubuntu), so it might be that you're encountering a situation where the podman configuration there is the culprit.

Would have to censor a lot from podman info, as quite a few things in this output are sensitive. That's why I did not include it from the beginning.

podman version give the same output as inside an Ubuntu VM.
podman images just list all the images including Dangerzone.
podman run hello-world works as expected.

Closing this issue, apparently a Pop!OS issue, works on Fedora as expected.

Okay, if you can, check that you're not using the VFS driver, as it's known to be buggy (see #1011)
