How to install git

Installing and setting up git on your computer

This article needs testing.

To really use the benefits of git you need to install it to your computer and set it up to work with SSH Keys .

Install git

sudo apt install git-all

# set your username and email
git config --global "John Doe"
git config --global

Set up the SSH key pair

If you do not already have one, generate a SSH Key pair :

ssh-keygen -t rsa -b 4096 -C "<YOUR-EMAIL-ADDRESS>"

A private and a public key will be saved on your computer. Usually you will find them at ~/.ssh/. The files will be called id_rsa and, where the file with the name ending ‘pub’ is the public key.

Transfer the public key to your GitLab profile

On the website of your GitLab instance, go to your User Settings->SSH Keys and paste the content of your public key. Be careful to copy the key exactly, without any spare spaces or end-of-line characters!
