UBUNTU 23.04 Desktop Installation
Before you begin, ensure that you have a storage plan and raid configuration (Servers) on your systems. It is recommended that you install Ubuntu on a separate disc to protect your data in the scenario where the OS fails.
Download Ubuntu
An Ubuntu image can be downloaded from https://ubuntu.com/download/desktop. In this KB, we'll be using the Ubuntu 23.04 release, which practices the new Ubuntu Desktop setup, which will be included in all future Ubuntu releases. Unlike Ubuntu Desktop, Ubuntu Server does not come with a graphical installation program. It instead uses a text-based menu-based process. If you prefer graphical interaction, you can install the desktop version.
If you're installing an older version of Ubuntu, such as 22.04 LTS, the visual presentation of the installer will be different, but the overall flow should be the same.
