How to Install Git on Ubuntu 24.04 LTS (Linux) | Step-by-Step Guide

Git is an essential tool for version control and collaborative software development. This step-by-step guide will show you how to install Git on Ubuntu 24.04 LTS, ensuring you have the latest version and can start managing your code efficiently. Follow these instructions to get Git up and running on your Ubuntu system.

**Step-by-Step Instructions:**

**Step 1: Open Terminal**
1. Press `Ctrl + Alt + T` or search for “Terminal” in the Applications menu to open a terminal window.

**Step 2: Update Package List**
1. Before installing new packages, it’s a good practice to update your local package index. Run the following command:
“`bash
sudo apt update
“`

**Step 3: Install Git**
1. With the package index updated, you can now install Git using the following command:
“`bash
sudo apt install git
“`
2. Confirm the installation by typing `y` when prompted.

**Step 4: Verify the Installation**
1. Once the installation is complete, verify that Git was installed correctly by checking its version:
“`bash
git –version
“`
2. You should see output indicating the version of Git installed, such as `git version 2.x.x`.

**Step 5: Configure Git**
1. It’s important to configure Git with your name and email address. This information will be used for your commit messages. Run the following commands, replacing “Your Name” and “your.email@example.com” with your actual name and email:
“`bash
git config –global user.name “Your Name”
git config –global user.email “your.email@example.com”
“`
2. To verify your configuration, you can use the following command:
“`bash
git config –list
“`
3. You should see a list of your configured settings, including `user.name` and `user.email`.

**Step 6: Set Up SSH Keys (Optional)**
1. If you plan to use Git with remote repositories, especially on platforms like GitHub or GitLab, setting up SSH keys is a secure way to authenticate.
2. Generate a new SSH key with the following command, replacing your email:
“`bash
ssh-keygen -t ed25519 -C “your.email@example.com”
“`
3. Follow the prompts to save the key (usually in the default location) and enter a passphrase if desired.
4. Add your SSH key to the SSH agent:
“`bash
eval “$(ssh-agent -s)”
ssh-add ~/.ssh/id_ed25519
“`
5. Copy your SSH key to your clipboard:
“`bash
cat ~/.ssh/id_ed25519.pub
“`
6. Add the SSH key to your Git hosting service (e.g., GitHub, GitLab) by pasting it into the appropriate section of your account settings.

**Additional Tips:**
– **Git GUI Tools**: If you prefer a graphical interface, you can install Git GUI tools such as `gitg` or `GitKraken`:
“`bash
sudo apt install gitg
“`
– **Documentation and Help**: For more information on using Git, refer to the official Git documentation at [Git Documentation](https://git-scm.com/doc) or use the `git help` command to access built-in help:
“`bash
git help
“`

By following these steps, you can install and configure Git on your Ubuntu 24.04 LTS system, allowing you to manage your code repositories effectively. Happy coding!
