Ubuntu 12.04 – How to Completely Uninstall / Remove the Kubuntu Desktop

These instructions are for Ubuntu 12.04 running the Unity desktop on which the Kubuntu Desktop was installed using either the Ubuntu Software Center or sudo apt-get on the command line.

The instructions may be the same for other versions of Ubuntu, but no guarantee is made.

When the Kubuntu Desktop is installed in Ubuntu 12.04, it installs several packages and libraries it requires as well as some optional packages. Not all these packages and libraries are uninstalled when you uninstall Kubuntu Desktop. Several packages (like dolphin and kmail) do not get uninstalled.

Quick Uninstall

This is not recommended because it will remove all packages normally installed with Kubuntu Desktop. This may include packages you previously installed (like dolphin or kmail) or packages that were installed when you installed some other program.

Note: this uninstall command assumes Kubuntu Desktop was installed on a fresh Ubuntu 12.04.

1) Open a terminal (instructions can be found here).

2) Enter the following command (it is very long and a single line):

sudo apt-get purge --auto-remove akonadi-backend-mysql akonadi-server akregator amarok amarok-common amarok-utils  apport-kde apturl-kde ark bluedevil cdparanoia cdrdao cryptsetup docbook-xsl  dolphin

It is easiest to copy the line and paste it into the terminal (right-click on the terminal and select Paste from the popup menu).

Preferred Uninstall

The better way to uninstall it is to follow the directions on this page.

This will show you on how to uninstall only the packages that were installed when Kubuntu Desktop was installed. The instructions are generic and work for any installed package.

It involves:

  1. identifying which packages were installed and
  2. creating a command to uninstall only those packages

It leaves intact any packages you may have installed (like dolphin or kmail) or were installed previously as part of other packages instead of blindly assuming that they were installed along with Kubuntu Desktop.
