Error Installing - Fresh Rasbian Lite Stretch

[Tollbringer]

Hello-

EDIT: I am very sorry - I forgot to say thank you for this script.
EDIT2: It seems to be resolved.

1. I rebooted the Pi.
2. I performed $ sudo apt-get upgrade before re-running the script. It terminated normally and left HomeAssistant installing. I am currently waiting for this to complete.

---

I am getting this error immediately following " Install Supervisor Docker "

Error response from daemon: error parsing HTTP 404 response body: invalid character 'p' after top-level value: "404 page not found\n"

"
Any ideas?
