How to Install Git and Connect to GitHub on Ubuntu

Git is the backbone of modern software development. If you're using Ubuntu and want to collaborate, version-control your projects, or contribute to open source, installing and setting up Git along with your GitHub account is one of the first steps. This guide will take you through the entire process in a clear, practical way.

Step 1: Update Your System

Before installing new software, it’s good practice to update your package index:

sudo apt update

Step 2: Install Git on Ubuntu

Git is available in Ubuntu’s default repositories. Simply run:

sudo apt install git

Once done, verify the installation:

git --version

You should see output like:

git version 2.34.1

This confirms that Git is installed.

Step 3: Configure Your Identity in Git

Git records who makes each commit. Set your user name and email address (should be the same email associated with your GitHub account):

git config --global user.name "Your Name"
git config --global user.email "youremail@example.com"

You can check this configuration by running:

git config --list

Step 4: Generate SSH Keys for Secure Communication

Instead of typing your username/password every time you push or pull code from GitHub, you can set up SSH keys.

Generate a new SSH key pair using:

ssh-keygen -t ed25519 -C "youremail@example.com"

Note: If you are using an older system that might not support Ed25519, use:

ssh-keygen -t rsa -b 4096 -C "youremail@example.com"

When prompted about where to save the key, press Enter for default location (~/.ssh/id_ed25519). Set a passphrase or leave it empty.

Step 5: Add Your SSH Key to the SSH-Agent

Start the ssh-agent in the background:

eval "$(ssh-agent -s)"

Add your private key:

ssh-add ~/.ssh/id_ed25519

Step 6: Add Your SSH Public Key to Your GitHub Account

Now you need to add the public SSH key (id_ed25519.pub) to your Github profile.

Display it with:

cat ~/.ssh/id_ed25519.pub

Copy that output fully.

Then:

1. Log in to your GitHub account.
2. Navigate to Settings > SSH and GPG keys.
3. Click New SSH key, give it a title like “Ubuntu Laptop,” and paste the copied key.
4. Save it.

Step 7: Test Your Connection

Run this command to test communication with GitHub over SSH:

ssh -T git@github.com

You might see a warning about authenticity—type yes to continue.

Successful reply example:

Hi username! You've successfully authenticated, but GitHub does not provide shell access.

Step 8: Clone a Repository From GitHub (Example)

To check everything works end-to-end, try cloning one of your repos:

git clone git@github.com:username/repository.git

Replace username and repository.git with your actual credentials.

If cloning succeeds without password prompts, you’re all set!

Bonus Tips

• Use git status often within repos to check changes.
• Consider installing GUI tools such as GitKraken or Git GUI if command line isn’t your preference.
• Explore branching workflows like git branch, git checkout, and git merge once comfortable with basics.

Conclusion

Installing and configuring Git on Ubuntu is straightforward and puts you on solid footing for all kinds of development projects. By pairing it securely with your GitHub account via SSH keys, you make pushing code fast and safe without repeatedly entering passwords.

Now that you have this setup complete, why not start by creating a new repository or contributing to an open-source project today? Happy coding!
