Crash on scaleway server

[whoabuddy]

From @pradel in Discord:

Hello, I took some time to try your script this morning, and I am having issues when running the bash script.

I created a new scaleway server (I tried both with ubuntu 20.04 and 18.04), and when I run the script right after nvm installation I hit the /root/.bashrc: line 6: PS1: unbound variable error

Full error log

Determined this is likely an issue with running as root user and nvm installation, still investigating.

Maybe check if user is root, display an error, then exit instead?
