This comprehensive guide walks you through the process of upgrading from older versions of Ubuntu to the latest and greatest: Ubuntu 20.04 Focal Fossa. We'll break down the steps into easy-to-follow instructions, ensuring a smooth and successful transition. So, let's dive in!

Before You Begin

Before we embark on this upgrade journey, it's essential to prepare your system. A little preparation goes a long way in ensuring a hassle-free experience.

1. Back Up Your Data

This might sound obvious, but it's crucial. Back up all your essential data: documents, pictures, music, and any other files you can't afford to lose. We recommend backing up to an external hard drive or cloud storage service. This backup is a safety net, ensuring you can recover any lost data in case something unexpected happens during the upgrade.

2. Update Your System

Before upgrading to Ubuntu 20.04, it's essential to ensure your existing system is up-to-date. Open a terminal and run the following commands:

sudo apt update
sudo apt upgrade

These commands download the latest software updates and patch any security vulnerabilities.

3. Check Hardware Compatibility

While Ubuntu 20.04 boasts excellent hardware compatibility, it's always a good idea to verify that your computer's components are supported. Check the Ubuntu release notes or consult the Ubuntu community forums for any known compatibility issues.

4. Free Up Disk Space

Ubuntu 20.04 requires a minimum of 25 GB of free disk space. Before starting the upgrade, clean up your system by removing unnecessary files, deleting unused applications, and freeing up any disk space you can.

5. Choose Your Upgrade Method

There are two primary ways to upgrade to Ubuntu 20.04: using the do-release-upgrade command or performing a clean install.

  • Using do-release-upgrade: This method is recommended for most users and provides a straightforward way to upgrade your existing system. It's a non-destructive upgrade, meaning it preserves your data and configuration files.

  • Clean Install: A clean install involves wiping your hard drive and installing Ubuntu 20.04 from scratch. While this approach requires more effort, it can be a good option if you're experiencing problems with your current system or want a fresh start.

Upgrading with do-release-upgrade

Let's begin the upgrade process using the do-release-upgrade command. This method is ideal if you're confident with your system and prefer a more streamlined approach.

1. Open a Terminal

Open a terminal window by pressing Ctrl+Alt+T.

2. Run the do-release-upgrade Command

Type the following command in the terminal and press Enter:

sudo do-release-upgrade -d

This command will initiate the upgrade process. The -d flag ensures that you're prompted to confirm the upgrade before it begins.

3. Follow the On-Screen Instructions

The upgrade process will take some time, depending on your internet speed and the size of your system. You'll be guided through the steps with on-screen prompts and messages. Follow the instructions carefully and accept the terms and conditions when prompted.

4. Confirm Your Upgrade

You'll be asked to confirm the upgrade. Type y and press Enter to proceed. The system will download the necessary files and apply the upgrade.

5. Restart Your System

Once the upgrade is complete, you'll be prompted to restart your system. Select "Restart Now" to complete the upgrade.

6. Verify the Upgrade

After your system restarts, log in. Open a terminal and run the following command to verify that you're now running Ubuntu 20.04:

lsb_release -a

This command will display information about your Ubuntu distribution, including the release name and version number.

Upgrading with a Clean Install

If you opt for a clean install, you'll need to create a bootable USB drive containing the Ubuntu 20.04 installation media. Here's how to do it:

1. Download the Ubuntu 20.04 ISO Image

Restart your computer and enter the BIOS settings. Change the boot order to boot from the USB drive first. Save the changes and exit the BIOS.

4. Install Ubuntu 20.04

Follow the on-screen instructions to install Ubuntu 20.04. You'll have the option to choose your preferred installation type, language, and partition scheme.
