I will show you the step-by-step installation KDE Plasma desktop environment on an Ubuntu 18.04 (bionic beaver).


  • A server running one of the following operating systems: Ubuntu 18.04 (bionic beaver).
  • 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).
  • 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.
