Step 1: Update Ubuntu

Before installing the Unity desktop environment, update your Ubuntu operating system to have all existing packages up-to-date.

sudo apt update && sudo apt upgrade

Step 2: Install Unity Desktop Environment

When installing the Unity desktop environment, you have three options: minimal, standard, or complete. Each option has advantages and disadvantages depending on your specific needs and preferences. The minimal installation includes the minimum necessary to run Unity and is best for users who want a lightweight, fast desktop environment. The standard installation consists of commonly used applications and features and is best for most users. The complete installation includes all available features and applications and is best for users who want a fully-featured desktop environment.

Before you begin, for Ubuntu 22.04 LTS users, you need to ensure the following package is installed, or you may not be able to log in to Unity.

sudo apt install dbus-x11

The first installation option is minimal installation. Run the following command to install.

sudo apt install ubuntu-unity-desktop --no-install-recommends

The minimal installation option of the Unity desktop environment is best suited for testing or those with older hardware. It includes only the bare necessities to run the environment and comes at around 80-100MB to download, with an additional 280-300MB of space required for installation.

Next, you can install the standard installation of Unity desktop environment with the following command.

sudo apt install ubuntu-unity-desktop

The standard installation of the Unity desktop environment is the most commonly recommended option for the average desktop user, as it provides a balance of features and performance. This installation package takes around 250-300MB to download and requires an additional 1600-1700MB of space.

The last option is to install the whole experience of the Unity desktop environment with the following command.

sudo apt install ubuntu-unity-desktop --install-suggests

The complete installation of the Unity desktop environment includes all available features and applications. However, it can add unnecessary “bloat” to older systems with limited resources. On the other hand, newer methods may not benefit from this installation as it includes many applications that may not be needed, such as firebird, jackd2, etc. It is recommended to be installed separately. This installation package requires a significant download of 3GB, and an additional 16GB of space is needed. Unless you have a specific need for this installation, it is recommended to stick with the standard installation for a balance of features and performance.
