RHEL 6.5 no AWS, yum: Não é possível recuperar metadados do repositório devido a 404 Não encontrados

Question

Eu tenho uma instância do RHEL 6.5 EC2 e o yum está quebrado

yum clean all

 $ yum clean all
Loaded plugins: amazon-id, rhui-lb, security
Cleaning repos: dag epel rhui-REGION-client-config-server-6 rhui-REGION-rhel-server-releases rhui-REGION-rhel-server-releases-optional
              : rhui-REGION-rhel-server-rh-common rhui-REGION-rhel-server-rhscl webmin
Cleaning up Everything

yum metadados limpos

 $ yum clean metadata
Loaded plugins: amazon-id, rhui-lb, security
Cleaning repos: dag epel rhui-REGION-client-config-server-6 rhui-REGION-rhel-server-releases rhui-REGION-rhel-server-releases-optional
              : rhui-REGION-rhel-server-rh-common rhui-REGION-rhel-server-rhscl webmin
0 metadata files removed
0 sqlite files removed
0 metadata files removed

Depois de limpo, tente atualizar a lista, mas resultar em erros 404

 $ yum list update

Eu também tentei a solução alternativa mencionada no fórum da AWS, mas não instalei o pacote link

Alguém pode fornecer algum conselho?
