Hello Linux Geeksters. In this article I will show you how to install or upgrade KDE to its latest version, KDE 4.10.4, which has just been released.
If you have KDE already installed, just add the repo, update the system and upgrade KDE:
$ sudo add-apt-repository ppa:kubuntu-ppa/backports
$ sudo apt-get update
$ sudo apt-get dist-upgrade
If you don’t have KDE, install KDE 4.10.4:
$ sudo add-apt-repository ppa:kubuntu-ppa/backports
$ sudo apt-get update
$ sudo apt-get install kubuntu-desktop
