I'm working using a Raspberry Pi Zero W, on a fresh install of Raspbian Buster (official)

running the script with :

curl https://raw.githubusercontent.com/lukicdarkoo/rpi-wifi/master/configure | bash -s -- -a Love test -c Mywifi password

I'll Be happy if you can help me to find a solution for this. :)

The variable NO_INTERNET is not set, so you can change:

"$NO_INTERNET"
to
"${NO_INTERNET-}"

Hope this helps.

@cropd thanks. Another solution would be to remove set -o nounset
