Comment 2 Yadnyawalk Tale 2020-11-30 17:38:42 UTC 
Red Hat Satellite 6.6 onward does not ship the MongoDB package; however, the product consumes MongoDB from Red Hat Software Collections (RHSCL) for Red Hat Enterprise Linux. Satellite has no plans to update to a version of MongoDB released with a Server Side Public License (SSPL) which includes all versions released after October 16, 2018. Refer to this article for more information: https://access.redhat.com/articles/5767021
