ubuntu Useful Commands

Update Ubuntu version

// Check Ubuntu Version
$: lsb_release -a

// Update your Current Ubuntu server to the latest:

// Step 1: This command refreshes your local list of software, 
// making a note of any newer revisions and updates. If there’s a newer version 
// of the kernel, the command will find it and mark it for download and 
//installation.
$: sudo apt-get update

// Step 2: The “dist-upgrade” switch asks Ubuntu to handle any dependencies  
// intelligently. That is, if a particular software package is dependent on 
// another software package to run, this command will make sure that the second 
// package is upgraded before upgrading the first one. This method is a safe way 
// to upgrade your Ubuntu Linux kernel. The kernel updates accessible through 
// this utility have been tested and verified to work with your version of Ubuntu.
$: sudo apt-get dist-upgrade

Install Node.js

// Install Node.js on Ubuntu
// One very convenient way to install Node.js is through a package manager of ubuntu
// Official Procedure: https://github.com/nodesource/distributions/blob/master/README.md

// Step 3: Install the Yarn package manager, run:
     curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
     echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
     sudo apt-get update && sudo apt-get install yarn
     
     // Yarn is a JavaScript package manager compatible with npm that helps 
     // you automate the process of installing, updating, configuring, 
     // and removing npm packages. It caches every download package and 
     // speeds up the installation process by parallelizing operations.
