When I remove the image, it output the error "image is in use by a container'. But there is no container.

We recently improved the error message to be more helpful (https://github.com/containers/podman/pull/15197). Try running `podman ps --external` which will list non-podman containers. Most likely, a `podman build` got killed on the machine and a so-called "build container" using this image is still running.

Kind regards,

Valentin
