Setup and Installation: Ubuntu how to upgrade Node.js

Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.

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.
