Some of yours facing issue with installing the latest version of NodeJs on Ubuntu 16.04 Server?
There is no "installation" per se, you just need to extract the tarball, and make sure the node and npm binaries in the ./bin subdirectory are somewhere in your path.
I find nvm is useful for managing node installations (it will download, extract, and add to path for you). If you want to do things manually, you can do something like:
wget https://nodejs.org/download/release/v10.5.0/node-v10.5.0-linux-x64.tar.gz
tar -xvf node-v6.9.2-linux-x64.tar.gz --directory /usr/local --strip-components 1
This will put the ./bin directory in /usr/local/bin, which should be in your $PATH already. You can verify that it worked with:
node --version
npm --version
Hope it helps.
