NPM will not install

While often I do not use Nodejs or NPM recently I wanted to run a socketio test which required NPM I followed the steps to install socketio and noticed npm was not properly working having installed it before I decided to uninstall it (all my issues really began here) once uninstalled I tried to reinstall I had got node reinstalled (tested with node -v) however when I tried to install NPM it threw errors
Code to install:

sudo apt-get install npm

Returned:

I have tried all kinds of solutions on the internet with no luck

sudo apt-get update
sudo apt-get upgrade
sudo npm install npm -g

Seemed to run with no errors but did not fix the issue

sudo apt-get update --fix-missing

fix missing result:

Many NPM commands that did not work as it is not installed

Probably tried like 20 other things as well this has been going on for about 3 days now any help to get my NPM reinstalled and working would be greatly appreciated
