Important Notice Before Installation

New users to Linux and novice users, create backups or plans if you do not like it and want to roll back before installing the desktop environment. Removing any Desktop Environment is challenging and will lead to system instabilities, and there are typically always remnant applications to remove, among other things.

Unless you have minimal system resources, having multiple desktop environments will not hinder your system. Often people have several and switch between, and it is advised to keep all the alternative desktop environments you install or reformat your system altogether.

Do not install the following desktop environment on your PC if this sounds too difficult or risky.

Install Unity Desktop Environment

The Unity Desktop has three installation choices minimal, standard, or complete. Each one has pros and cons depending on what you are looking to get out of the desktop. A brief explanation will be explained with each option.

Minimal Installation:

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

The minimum installation is suitable for testing, and having the bare minimum, older hardware would benefit from this version. Overall, the size is 76MB to download, and 280MB additional space is required afterward.

Standard Installation:

sudo apt install ubuntu-unity-desktop

The standard Unity installation is the most recommended for the average desktop user that wants a balance system. Overall, the size is 250MB to download, and 820MB additional space is required afterward.

Full Installation:

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

This comes with everything naturally being a complete installation, but it will add bloat, affecting older systems without enough resources. However, newer systems will probably not enjoy this installation since it will add many applications they will not use, such as firebird, jackd2, and others which should be installed one by one.

Overall, you will need to download a whopping 2GB, with 15GB of additional space required. Unless you need this installation expressly, it is advised to stick with the standard installation.
