Yes, exactly.
That isn't what I asked you to do, read my post again.

Is that the response to the command I suggested you try, in post #14? Namely
curl https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered
That will show whether curl is able to fetch the file. The fact that the bash <(curl ... command did nothing at all suggests that the curl command fetching the script failed.

Well that looks ok. But if you run the script
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
it does nothing? By which I assumed that you meant it just returned to the terminal prompt immediately.
Now the script has been able to load, and node-red-start already works, but it gives an error when starting.

Hi - the error
22 May 18:38:50 - [error] Error: port in use
most likely means that another instance of Node-RED is still running... either the old snap or another attempt you had to run it. You need to stop/kill whichever it is - if node-red then try node-red-stop - if the snap then try sudo snap stop node-red
Finally it worked perfectly. The problem is that to install these modbus nodes you have to do it by launching node-red from the terminal. Nod-red can be launched from ubuntu programs, but the node-red-stop commands don't work. That is why it gives the message that there is another process running.
Thank you very much to all. Remember those who work with ubuntu, you have to install the script.
I have continued to investigate the problem. It takes place when node-red is launched from ubuntu, and also from the terminal, the only way to stop it from the terminal is with sudo snap stop node-red. It would be necessary to know how it can be stopped permanently from Ubuntu.
