Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, and any other Ubuntu-based distribution
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
• It is prudent to take a backup of all your databases and files before embarking on any major upgrade of an operating system. This ensures you will not lose your data in case something goes wrong during the upgrade process.
