Before I get to your question, I wanted to add that I also ended up appending crun to the list of packages to update and that worked too. I forked your gist for my own notes.

@shvchk , thankfully, the repos are still present and after you mentioned this I downloaded the debs for safekeeping. This is the only clean way I have found to update podman from 3.4.4 to 4.x on 22.04 and I have searched for hours on this topic. It's sad how complicated this is to update. This is the only method that seemed "clean". Please enlighten me if you have come across a clean way to keep podman fresh on 22.04. I haven't considered compiling from source yet but I'm almost there...

This may have worked three weeks ago, but it doesn't appear to anymore:

E: The repository 'http://archive.ubuntu.com/ubuntu lunar 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.

I haven't been able to find any way around it after about an hour of Googling. Sad. I guess I have to switch back to Docker. Podman is completely broken in Ubuntu 22.04 with a known bug that the Ubuntu maintainers seem unconcerned with fixing.
