Resolution

1. Confirm that the satellite-capsule-6.15-for-rhel-8-x86_64-rpms repository is enabled on the Capsule server by examining the output of the following command:

# dnf -C repolist

2. If the satellite-capsule-6.15-for-rhel-8-x86_64-rpms repository is not enabled on the system enable it using the following command:

# subscription-manager repos --enable=satellite-capsule-6.15-for-rhel-8-x86_64-rpms

3. Retry the failed command to configure the Capsule server with the SSL certificates.
