I think this is the result of not installing either Fedora or Debian as the default VMs need a template to be based on.
You will have to take quite a bit of time to dig into the system to get this running on your own in my opinion. The documentation lacks some parts and is not really as helpful here in my personal opinion. Other parts appear to be outdated. I may have missed something though. The initial setup you are describing is a tool you can find on the OS and on GitHub. I did a dive into that for my installation issues. I will add a post related to that in my thread in a moment: Installer corrupts installation medium (+ bounty for help)
