i am trying to set up NR on a RPi 3b. I tried to install it using this command: bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
Unfortunately the installation fails at installing NR core:
It turned out that I set static addresses for ip and gateway for eth0 to connect it to the company network.
For some reason these settings also apply to wlan0 if not configured.
So I set up a wlan0 interface and afterwards it worked.
Learned something new
