The steps in warning state itself might not mean there is an error,
but it should be reviewed to ensure the behavior is expected

Resolution

Please ensure that all repositories required by Satellite 6.11 on RHEL 7 as well as the Extras repository required by leapp are enabled.

The following command will enable all required repositories including RHEL 7 Extras:

# subscription-manager repos --enable=rhel-7-server-rpms \
--enable=rhel-server-rhscl-7-rpms \
--enable=rhel-7-server-ansible-2.9-rpms \
--enable=rhel-7-server-satellite-6.11-rpms \
--enable=rhel-7-server-satellite-maintenance-6.11-rpms \
--enable=rhel-7-server-extras-rpms
