How do I install KDE?

Solution 1:

You need to install the kubuntu-desktop package for the full install.

The GUI method would be to click this button:

Install via the software center
(source: hostmar.co)

The command line method would be:

sudo apt-get install kubuntu-desktop

Then the next time you login you can choose what to use from the login screen (under Session).

Solution 2:

To get just the plasma environment (on 12.04 and newer):

sudo apt-get install plasma-desktop

It worked fine for me on 15.10

Solution 3:

If you want to log in from KDE run sudo apt-get install kdm, sudu apt-get remove gdm, and dpkg reconfigure kdm.

Solution 4:

Just try the following command in a terminal

sudo apt-get install kubuntu-desktop

Then just select KDE on the login manager.
