Purge existing packages installed via package manager

sudo apt purge nodejs npm mongodb; sudo apt autoremove;

Install Node (original source: https://github.com/nodejs/help/wiki/Installation):

Download NodeJs from website: https://nodejs.org/dist/v20.12.2/node-v20.12.2-linux-x64.tar.xz

Edit version number below and keep it same as your downloaded file name. The snippet also exports path:

VERSION=v20.12.2
DISTRO=linux-x64
sudo mkdir -p /usr/local/lib/nodejs
sudo tar -xJvf node-$VERSION-$DISTRO.tar.xz -C /usr/local/lib/nodejs
export PATH=/usr/local/lib/nodejs/node-$VERSION-$DISTRO/bin:$PATH
. ~/.profile

Above snippet modifies also PATH. Those who wish to create a symlink instead can follow this:

VERSION=v20.12.2
DISTRO=linux-x64
sudo ln -s /usr/local/lib/nodejs/node-$VERSION-$DISTRO/bin/node /usr/bin/node
sudo ln -s /usr/local/lib/nodejs/node-$VERSION-$DISTRO/bin/npm /usr/bin/npm
sudo ln -s /usr/local/lib/nodejs/node-$VERSION-$DISTRO/bin/npx /usr/bin/npx

Check if installed components output normally:

node -v
npm
npx -v
