.Unable to build ISOs from a signed container

Trying to build an ISO disk image from a GPG or a simple signed container results in an error, similar to the following:

----
manifest - failed
Failed
Error: cannot run osbuild: running osbuild failed: exit status 1
2024/04/23 10:56:48 error: cannot run osbuild: running osbuild failed: exit status 1
----

This happens because the system fails to get the image source signatures. To work around this issue, you can either remove the signature from the container image or build a derived container image. For example, to remove the signature, you can run the following command:

----
$ sudo skopeo copy --remove-signatures containers-storage:registry.redhat.io/rhel9-beta/rhel-bootc:9.4 containers-storage:registry.redhat.io/rhel9-beta/rhel-bootc:9.4
$ sudo podman run \
       --rm \
       -it \
       --privileged \
       --pull=newer \
       --security-opt label=type:unconfined_t \
       -v /var/lib/containers/storage:/var/lib/containers/storage \
       -v ~/images/iso:/output \
       quay.io/centos-bootc/bootc-image-builder \
       --type iso --local \
       registry.redhat.io/rhel9-beta/rhel-bootc:9.4
----

To build a derived container image, and avoid adding a simple GPG signatures to it, see the link:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/building_running_and_managing_containers/assembly_signing-container-images_building-running-and-managing-containers[Signing container images] product documentation.

Workaround

Remove the signature from the container image:

$ sudo skopeo copy --remove-signatures containers-storage:registry.redhat.io/rhel9-beta/rhel-bootc:9.4 containers-storage:registry.redhat.io/rhel9-beta/rhel-bootc:9.4
$ sudo podman run \
