Hi Laurent You can install the crun package to fix the service error ( I suppose you found that out already)
You can find an intro about podman and varlink here: https://podman.io/blogs/2019/01/16/podman-varlink.html I think there is a problem in the Depends of podman: https://salsa.debian.org/debian/libpod/-/blob/master/debian/control#L95 has a depends on crun OR runc but you need actually both, runc for the command line tool, and crun for the varlink service. $ podman list images Error: could not get runtime: default OCI runtime "runc" not found: invalid argument is what you get when installing podman without runc.
