How to update Ubuntu via CLI

I run a small Ubuntu Server VM on Azure which I mainly use for test & dev, but I always seem to forget how to update Ubuntu from the CLI. ┬áThis might be really easy stuff for the hardcore Linux users, but for Linux newbies like me whom are used to the Microsoft world I don’t remember commands like this as I don’t use them that often ­čÖé . ┬áHere is how to update Ubuntu:

sudo apt-get update        # Fetches the list of available updates
sudo apt-get upgrade       # Strictly upgrades the current packages
sudo apt-get dist-upgrade  # Installs updates (new ones)
