Install KDE Plasma using Tasksel on Debian 10/9

Tasksel is a Debian/Ubuntu tool that installs multiple related packages as a co-ordinated “task” onto your system. It is installed by default on the server editions. You also require aptitude command to run the installation. If neither of these packages are installed by default, then execute the command below to install them.

apt install aptitude tasksel

Next, you can install KDE Plasma Desktop by running the command below;

aptitude install ~t^desktop$ ~t^kde-desktop$

You can as well run the GUI installation by running tasksel with no option.


On Debian 10/9, select the Debian Desktop Environment and KDE [Plasma] as shown below.
