How to install KDE plasma desktop on Ubuntu 22.04 Jammy Jellyfish Linux

By default, Ubuntu 22.04 Jammy Jellyfish sports the GNOME desktop environment, or no GUI at all in the server edition. If you would like to change things up and install KDE Plasma instead, the GUI can be downloaded and installed directly from Ubuntu’s package repositories.

This can be done whether you are switching from GNOME to KDE Plasma, or you currently are running command line interface only and wish to install a graphical desktop environment. KDE Plasma is a great choice that comes with all the tools you will need to administrate your Ubuntu system.
