How can I upgrade my Ubuntu Server from version 20.04 LTS to 22.04 LTS while avoiding an upgrade to 24.04 LTS?

I’ve been running Ubuntu Server 20.04 LTS for a while now, and it’s been solid. Recently, though, I’ve read a lot about the features in 22.04 LTS, and I think it’s time to make a move. The problem is, I’ve heard some mixed things about how the upgrade process works, especially with version 24.04 LTS coming out not too long after. I really want to go to 22.04 LTS and skip right over 24.04 LTS, but I’m not sure how to do that effectively.

Here’s where my confusion starts—I’m not very experienced with these upgrades, and I definitely want to avoid being caught in some automatic upgrade that takes me all the way to 24.04 LTS. I’ve got a few applications and services running that I can’t afford to break right now. I read somewhere that sometimes the system might try to automatically upgrade to the latest LTS version if it’s available. How do I make sure I’m explicitly telling my server to stick with 22.04 LTS?

Also, I’m curious if there are specific steps I should follow or any precautions to take before I start this upgrade process. Is it really as simple as running a few commands, or should I be backing things up in a more thorough way? I’ve heard horror stories about upgrades going wrong, leaving users with broken systems and lost data.

Another thing on my mind is whether to upgrade directly from the command line or if it’s better to do something like a fresh install. I’ve got some experience managing servers, but when it comes to upgrades, it feels a bit daunting.

If anyone has gone through this specific upgrade path before, especially with the intention of staying away from 24.04 LTS, I’d appreciate your insights. What worked for you? Any advice would be super helpful as I navigate this transition while keeping my server stable and reliable. Thanks in advance!

    1. Ubuntu Server Upgrade Advice

      Upgrading to Ubuntu Server 22.04 LTS

      Looks like you’re in a bit of a pickle about upgrading your Ubuntu Server 20.04 LTS to 22.04 LTS, especially with 24.04 LTS looming around! Totally get that feeling of trying not to break stuff you already have running.

      How to Avoid Automatic Upgrades

      First off, let me reassure you: you can prevent your server from jumping to 24.04 LTS. When you start the upgrade process to 22.04 LTS, use the command:

              sudo do-release-upgrade

      This should get you to 22.04 LTS without forcing a jump to the next version. But to be extra safe, check your upgrade settings in the file /etc/update-manager/release-upgrades.

      Backup, Backup, Backup!

      Before you do anything, BACK UP YOUR DATA! Seriously. You don’t want to end up like those horror stories you mentioned. Use tools like rsync or tar to create backups of your important files and config settings.

      Upgrade Steps

      Here’s a simple step-by-step:

      1. Update your current system:
        sudo apt update && sudo apt upgrade
      2. Backup your data!
      3. Run the upgrade command mentioned above.
      4. Follow the prompts and watch the magic happen.

      It’s generally fine to do it from the command line, especially since it’s a server. A fresh install can be less stressful if you want to start fresh, but it’ll take more time to get everything back to how you like it.

      Final Thoughts

      Just make sure you read any prompts carefully during the upgrade process. And don’t hesitate to check the official Ubuntu documentation or forums if you hit a snag! Good luck, and may your server stay stable!



    2. Upgrading from Ubuntu Server 20.04 LTS to 22.04 LTS while avoiding an automatic upgrade to 24.04 LTS is entirely feasible. First, to prevent unwanted auto-upgrades, you should adjust your settings to specify the release upgrader preference. Open your `/etc/update-manager/release-upgrades` file, and set the `Prompt` option to `lts`. This makes sure that your system will only prompt you for upgrades to the next LTS version, thereby keeping it on track for 22.04 LTS. Additionally, ensure that your package information is up to date with `sudo apt update` and `sudo apt upgrade` before starting the upgrade process to prevent any conflict with residual packages from your previous release.

      Before you begin the upgrade, it is essential to create a comprehensive backup. This should include your configuration files, databases, and any other critical data that your applications rely on. Use tools such as `rsync` or `tar` for file backups and ensure your databases are properly exported. While directly upgrading via the command line using the command `sudo do-release-upgrade` is straightforward, consider evaluating the option of a fresh install if you have the means; it allows for a cleaner setup without legacy issues. Whichever method you choose, thoroughly ensure that your applications are compatible with 22.04 LTS and consult their documentation for any required changes to config files or dependencies as you prepare for this upgrade.
