Install KDE Plasma on Linux Mint 21

In this tutorial, we will show you how to install KDE Plasma on Linux Mint 21. Are you tired of the default user interface on your Linux Mint 21? Do you want to give your desktop a new and fresh look? Look no further than KDE Plasma, one of the most customizable and feature-packed desktop environments available for Linux.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of KDE Plasma on Linux Mint 21 (Vanessa).


  • A server running one of the following operating systems: Linux Mint 21 (Vanessa).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for KDE Plasma.
  • 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.

Install KDE Plasma on Linux Mint 21

Step 1. Before running the tutorial below, it’s important to make sure your system is up to date by running the following apt commands in the terminal:
