1. Obtain the installation source

apt-get upgrade
3. If the KED desktopis not installed in the system, then execute the following command to install
apt-get install kubuntu-desktop
4. Errors may occur during the installation process: kde-config-telepathy-accounts package conflicts, as shown below:

sudo dpkg-reconfigure gdm
