Hello
as a dumb user of linux, i am not able to install "sfbspot-config".
It aborts with the error message "Failed to get username".

OK, I see... you're logged in as root

Either login as user pi or remove sudo from the command line like this:
curl -s https://raw.githubusercontent.com/sbfspot/sbfspot-config/master/sbfspot-config|bash
