How can I set up an older version of Ubuntu?

One of the most well-known Linux distributions, Ubuntu, frequently releases new versions with upgraded functionality. There are circumstances, nevertheless, in which you might want to install an older version of Ubuntu. This can be due to program constraints, compatibility issues, or even just personal choice. We'll walk you through the process of installing an earlier version of Ubuntu on your computer in this guide.

1. Choose the Right Version

You must choose which previous version of Ubuntu you want to install before you can proceed. To view a list of all accessible versions, go to the official Ubuntu release page (https://releases.ubuntu.com/). Generally speaking, older releases have labels such as "Previous LTS Releases" or "Previous Releases." Versions with LTS (Long Term Support) are advised for stability and long-term use.

Choose the version that best meets your requirements while taking into account elements like software compatibility and support duration. Standard releases are supported for nine months, while LTS versions are supported for five years. Once you've decided, download the desired Ubuntu version's ISO image.

2. Create a USB Drive That Boots

You will require an USB-bootable device with the installation media in order to install Ubuntu. Tools like "Rufus" on Windows or "Etcher" on Windows, macOS, or Linux can be used to make one. Here is a general description of what happens:

1. Connect a USB drive to your computer that is at least 8GB in size.

2. Download the Ubuntu ISO image for the pre-selected older version.

3. Create a USB using a tool (such as Rufus, Etcher, etc.).

4. As the source, choose the Ubuntu ISO file you downloaded.

5. Decide where you want the USB drive to go.

6. Starting the procedure will cause the utility to produce a bootable USB stick containing the Ubuntu installation media.

3. Start up using the USB drive

You must start your computer from the bootable USB device once it is prepared. This often entails going into the BIOS or UEFI settings on your computer and altering the boot order to give the USB drive priority. Depending on the maker and type of your computer, the specific steps could change.

1. Switch off your computer.

2. You'll see a notification (often displayed momentarily) during the boot process that instructs you which key to hit to access the BIOS or UEFI settings. Common keys include Del, ESC, F2, and F12.

3. Make your way to the BIOS or UEFI settings.

4. Choose "Boot" or "Boot Order" from the menu.

5. Make the USB drive the first boot option by altering the boot order.

6. Exit the BIOS or UEFI settings after saving the modifications.

7. As soon as your computer starts up, the Ubuntu installation environment will be launched from the USB device.

4. Download Ubuntu

1. You can start the installation procedure once the Ubuntu installation environment has loaded:

2. To install Ubuntu, select your favored language and press "Install Ubuntu."

3. Select a keyboard layout.

4. If necessary, join a Wi-Fi network.

5. If you want to switch to an older version of Ubuntu, choose "Erase disk and install Ubuntu" on the "Installation Type" box. Be careful because doing this will remove all of the data on your disk. Alternately, select "Something else" to manually partition the drive.

6. Set your time zone, make a user account, and select your login information by following the on-screen instructions.

7. After reading the installation summary, click "Install" when you're ready.

8. The setup procedure will start. You'll be asked to remove the installation media (the USB device) and hit Enter when it's finished.

9. As soon as your computer restarts, you will see the login screen for the freshly installed earlier version of Ubuntu.

Conclusion

The correct version of Ubuntu must be chosen, a bootable USB drive must be created, the USB drive must be booted, and the installation procedures must be followed. Although it's normally advised to use the most recent LTS release for stability and long-term support, there are good reasons to choose an earlier version, such as software compatibility or particular needs.

Consider your use case and security requirements carefully before selecting an earlier release of Ubuntu because those releases may only receive limited maintenance and security upgrades.
