Ubuntu how to upgrade Node.js

I was running a Node service on Ubuntu and I was stuck on an old Node.js version.

Here’s what I did to update to the latest available:

curl -sL https://deb.nodesource.com/setup_18.x | sudo -E bash -

sudo apt-get install -y nodejs

The https://deb.nodesource.com/setup_18.x script points to the LTS version.

Change that number to 19, like https://deb.nodesource.com/setup_19.x, to use the current version.

And if 20/21 are out, just change that number.
