KDE 4 has been released. I’ve received couple of questions about installing KDE 4 under Ubuntu Linux 7.10. KDE 4 Packages are available for Ubuntu Linux version 7.10 (Gutsy) and from development Ubuntu Linux Hardy version. They install to /usr/lib/kde4 and can be installed alongside your existing KDE 3. However these packages are not compatible with KDE 4 beta packages. Following simple step will help you install KDE 4.
How do I install KDE 4 under Ubuntu Linux?
First you need to update Ubuntu package source file.
WARNING! These examples may crash your Desktop as KDE v4.0 packages are not 100% compatible with Ubuntu 7.10. Following instructions worked on my desktop but failed to work on Laptop. YMMV.Step # 1: Update Source File
Open a terminal
Open /etc/apt/sources.list file using a text editor such as vi or gedit, enter:
$ sudo vi /etc/apt/sources.list
OR
$ sudo gedit /etc/apt/sources.list
Append following line:
deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu gutsy main
Close and save the file. Type the following command to update package list:
$ sudo apt-get update
GUI tool to update software source
Alternatively, you can use GUI tool by visiting System > Administration > Software Sources > Third Party Software > Add > Enter url ‘deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu gutsy main‘ > Add Source > Update > Close

Step # 2: Install KDE 4 desktop
To install kde 4, enter:
$ sudo apt-get install kde4-core
You’ll get a warning when installing kde 4, just force to install the same without verification:
