This is a fantastic question.

Maybe you’ve already looked into this, but I checked the playbook and the error above is occuring when Ansible tries to run this command:

test -e /usr/bin/python || (apt -y update && apt install -y python3-minimal python3-setuptools)

If you manually run the part of the command in parentheses above you’ll probably get the Release file error also listed above, and from there you might be able to find out what’s up. I think that error usually has to do with your repository setup and/or the version of Ubuntu youre running, but Google can hopefully tell you for sure.

Ansible was a breeze once I got it going.

I could never get ansible to work when I was setting up the same machine.

Could you post your inventory file?
