We were not able to find or create Copr project packit/containers-podman-24021 specified in the config with the following error:

Packit received HTTP 500 Internal Server Error from Copr Service. Check the Copr status page: https://copr.fedorainfracloud.org/status/stats/, or ask for help in Fedora Build System matrix channel: https://matrix.to/#/#buildsys:fedoraproject.org.

---

Unless the HTTP status code above is >= 500, please check your configuration for:

1. typos in owner and project name (groups need to be prefixed with @)
2. whether the project name doesn't contain not allowed characters (only letters, digits, underscores, dashes and dots must be used)
3. whether the project itself exists (Packit creates projects only in its own namespace)
4. whether Packit is allowed to build in your Copr project
5. whether your Copr project/group is not private

Ephemeral COPR build failed. @containers/packit-build please check.

You can remove external containers with podman rm --force see the docs there. So the last sentence should stay otherwise users do not know how to remove them

agree with @Luap99 ... if you repush, we should be good. Thanks!

I think #7891 has already allowed users to remove external containers directly. No need for --force.

If they are not mounted it seems to work without so yes.
