Can't install the latest version of NodeJs despite update prior to the attempt

I'm updating the info on the available packages.

sudo apt-get update

Then, I'm installing NodeJs and NPM.

sudo apt-get install nodejs
sudo apt-get install npm

When finished, I get the message that the latest version is installed. I also verify it.

nodejs --version

It says that the version is 8.10.0. However, when I check on NodeJs' page, it says that the latest current version is 10.10.0 (and even the LTS version is higher, 8.11.4).

Clearly, I'm not getting the latest version and being a noob on Linux, I'm sure I've done something wrong, despite following a guide.

My version is, according to the "About", 18.04.1 LTS.

1. What am I missing in my ignorance?
2. How can I install the recent version of NodeJs?

Solution 1:

Use the NodeJS guide for installing the 10.x repo. These instructions are roughly copied here below:

Node.js is available from the NodeSource Debian and Ubuntu binary distributions repository (formerly Chris Lea's Launchpad PPA). Support for this repository, along with its scripts, can be found on GitHub at nodesource/distributions.

NOTE: If you are using Ubuntu Precise or Debian Wheezy, you might want to read about running Node.js >= 6.x on older distros.

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

Alternatively, for Node.js 10:

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs

Optional: install build tools

To compile and install native addons from npm you may also need to install build tools:

sudo apt-get install -y build-essential

Available architectures:

• i386 (32-bit)
• amd64 (64-bit)
• armhf (ARM 32-bit hard-float, ARMv7 and up: arm-linux-gnueabihf)
