Encountered an issue while following the official Red Hat documentation for setting up Insights Advisor in a disconnected environment:

Reference: Red Hat Satellite 6.17 - Disconnected Environment Guide :
https://docs.redhat.com/en/documentation/red_hat_satellite/6.17/html-single/installing_satellite_server_in_a_disconnected_network_environment/index#installing-advisor-engine-using-import-and-export

The issue arises when attempting to copy the Satellite Advisor Engine image using skopeo in preparation for import into the disconnected Satellite server.

Steps to Reproduce

1. Run the following command to copy the image using skopeo:

   # skopeo copy containers-storage:registry.redhat.io/satellite/iop-advisor-engine-rhel9:6.17 oci-archive:/tmp/iop-advisor-engine.tar

   Observed Error:

   INFO[0000] Not using native diff for overlay, this may cause degraded performance for building images: kernel has CONFIG_OVERLAY_FS_REDIRECT_DIR enabled 
   FATA[0000] initializing source containers-storage:[overlay@/var/lib/containers/storage+/run/containers/storage:overlay.mountopt=nodev,metacopy=on]registry.redhat.io/satellite/iop-advisor-engine-rhel9:6.17: reference ... does not resolve to an image ID

1. If you manually pull the image using podman:

   # podman pull registry.redhat.io/satellite/iop-advisor-engine-rhel9:6.17

   Image is successfully pulled and stored in local container storage.

1. Attempt to export the pulled image again using skopeo:

   # skopeo copy containers-storage:registry.redhat.io/satellite/iop-advisor-engine-rhel9:6.17 \
   oci-archive:/tmp/iop-advisor-engine.tar

   New Error:

FATA[0000] Can not copy signatures to oci-archive:/tmp/iop-advisor-engine.tar:: 
Pushing signatures for OCI images is not supported

Expected Behavior

• • The image should be exportable using the documented skopeo copy method for use in a disconnected Satellite environment.

Actual Behavior

• • skopeo fails to locate the image unless it is pulled first.
