What were you trying to do that didn't work?

I'm trying to set up testing of podman/cockpit-podman on CentOS/RHEL 10. System containers are broken in multiple ways.

Please provide the package NVR for which bug is seen:

podman-5.0.2-1.el10.x86_64

How reproducible:

Always

Steps to reproduce

# podman run -it --rm quay.io/libpod/busybox
Error: netavark: unable to append rule '! -d 224.0.0.0/4 -j MASQUERADE' to table 'nat': code: 4, msg: Warning: Extension MASQUERADE revision 0 not supported, missing kernel module?

OK, that is already known (https://bugzilla.redhat.com/show_bug.cgi?id=2273078), so with the workaround:

# NETAVARK_FW=nftables podman run -it --rm quay.io/libpod/busybox
Error: OCI runtime error: crun: unknown version specified

This doesn't depend on the particular container image, it also happens e.g. on testing-farm with a different container image.
