Arduino node will not install?

The node installs ok for me on Ubuntu, with nodejs 16.
When you come to installing node-red use the Debian/Ubuntu/Pi script

I have now Ubunto up and run , and Arduino node is installed :slight_smile:

but now Node-red will not connect to the board ??

I also installed Arduino software and it can find the board and also the port :

/dev/ttyACM0 Serial Port (USB)

if I do a LSUSB then the Arduino board is on the list :slight_smile:

node-red@nodered-OptiPlex-7040:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 008: ID 2341:0042 Arduino SA Mega 2560 R3 (CDC ACM)
Bus 001 Device 002: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

so you can see that ubuntu is finding the Arduino board ???

but there is no way nod-red is connected to it :frowning:
