IMPORTANT: A legacy Oracle Linux yum server repo file was found. Oracle Linux yum server repository configurations have changed which means public-yum-ol6.repo will no longer be updated. New repository configuration files have been installed but are disabled. To complete the transition, run this script as the root user:
