I am getting an error installing ambari-server-2.7.4.0 on Centos8. It seems as though it can't resolve conflict with python. Although I have Python36 installed, it is still asking for python2.6 or greater. I read your many responses but they did not help with my situation. Any support on this matter will be appreciated. Thanks.
The best technical reference before you embark on deploying your cluster is to check the compatibility of the different moving parts of HDP/Cloudera binaries against an operating system of your choice, the first source of truth is please filter all the possible valid options using supportmatrix cloudera/hortonworks tool
Hortonworks and Cloudera do run exhaustive tests on a particular Operating system before certifying it as production-ready and from the about RHEL/Centos 7.7 are not yet certified so I highly doubt whether RHEL/Centos 8 is certified that explains the Python errors you are encountering.
