This is my biggest problem too, and it's not just my problem but Podman's problem. Lack of name recognition is big for sure compared to Docker, but to me this version mismatch problem is higher on the list and more sure to keep Podman niche. Distros like Ubuntu always ship with older versions of software, it's sadly up to the maintainer to release newer versions, and Podman just doesn't seem interested in doing that. I don't know if it was their goal but it got me to use some RedHat derivative on my home server just to get a later version.
