How to replace desktop environment?

I wanted to figure this out on my own but have not been able to do so.

Specifically, I would like to add KDE Plasma Desktop as my desktop GUI environment. Is this simply impossible? I’ve attempted to do so through command line
$ apt-get install plasma-desktop

If anyone knows how to replace the default desktop environment, please let me know. Thanks!

and what do you see as output ?
