Hi alll

I have a problem when I deploy my flow, I am using arduino running firmata firmware and it has running fine when I usede a RPI but I am now using a Unbunto PC, all other nodes there is no problem when I deploy. I can see that the Arduino node is installed  
I have updated node - red to latest ver.

regards Bent

Welcome to the forum @Eskolin

Go into your .node-red directory and run  
`npm remove node-red-node-arduino`  
and then  
`npm install --unsafe-perm node-red-node-arduino`

If that shows any errors then paste the full output here please. Copy/paste not screenshot please.  
If it doesn't show an error then restart node-red and refresh the browser and see if it is now ok.

Did you doubleclick on 1 of the arduino-in nodes and configure it ?

Did you restart node-red and refresh the browser after the `npm install`?  
If you did then go into your .node-red folder and run  
`npm list node-red-node-arduino`  
Post the full output from that command, including the line with the command. Copy/paste, not screenshot please.
