Hi Dasgoll

Thanks for your valuable input, I have installed Python 3 with SCL to start the download and installation of ansible. now I see the containers in Docker and load the Ansible web page. but what happens is that it stays loading and never finishes updating. analyzing the log I see the following. I appreciate you can help me.
