Upgrading your VPS to the latest version of Ubuntu ensures you have the latest features, security updates, and performance improvements. In this tutorial, we’ll guide you through the process of upgrading from Ubuntu 22 to Ubuntu 24 on your VPS.

Why Upgrade to Ubuntu 24?

  • Long-Term Support (LTS): Ubuntu 24 comes with 5 years of security updates and maintenance.
  • New Features: Improved system performance, security, and support for new technologies.
  • Docker and App Compatibility: Keep your containers and applications running smoothly with the latest versions.

Prerequisites

Before upgrading, ensure that:

  • Your VPS is running Ubuntu 22.
  • You have SSH access to your server.
  • Your system is fully updated.
  • You’ve backed up your data, especially Docker containers or critical applications.

Step-by-Step Guide

1. Connect to Your VPS via SSH

ssh username@your_vps_ip

Replace username with your user and your_vps_ip with your server’s IP.

2. Update Your Current System

Ensure your system is up to date:

sudo apt update && sudo apt upgrade -y
sudo apt dist-upgrade -y
sudo apt autoremove -y

3. Install the Update Manager

If you don’t have the update manager installed, run:

sudo apt install update-manager-core

4. Check for Available Upgrades

Run the following command to check if Ubuntu 24 is available:

sudo do-release-upgrade -c

5. Upgrade to Ubuntu 24

If Ubuntu 24 is available, initiate the upgrade process:

sudo do-release-upgrade

Follow the prompts to complete the upgrade. You may be asked whether to keep or replace configuration files during the process.

6. Reboot Your VPS

Once the upgrade is complete, reboot your VPS:

sudo reboot

7. Verify the Upgrade

After rebooting, verify the upgrade by running:

lsb_release -a

You should see:

Distributor ID: Ubuntu
Description: Ubuntu 24.04 LTS
Release: 24.04
Codename: focal

Troubleshooting

  • Backup: Always ensure that important data is backed up before performing an upgrade.
  • Logs: If any errors occur during the upgrade, check logs in /var/log/dist-upgrade/ for more details.
