Well… KDE 4.1 finally released on 29 july 2008. I’m quite happy about this. Right now, I’m going to give a tutorial to install KDE 4.1 inside your ubuntu. KDE 4.1 comes with a lot of innovations for the Linux desktop. KDE 4.1 is the next generation of the popular K Desktop Environment, which seeks to fulfill the need for a powerful yet easy-to-use desktop, for both personal and enterprise computing. The new version provides increased stability over the first KDE 4 version and more eye candy!

OK, this is the tutorial, read it carefully, and I also provide some apt-url to make the linux rookies more comfortable.

First, add KDE 4.1 repositories.
Go to System->Administration->Software Sources
Then click the second tab called “Third Party Software” then click the “add” button and paste the following code at the new windows:

deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main

After that, click the ‘Add Source’ button and, immediately after, the ‘Close’ button of the main window. After that, it will ask you to reload the repositories, and reload those repositories until in finish.

Secondly, Install KDE 4.1
If you’re in windows/other operating system now, here is the code:

sudo apt-get install kubuntu-kde4-desktop

If you’re in Ubuntu, just click this link to perform the installation automatically(apt-url):

When the download is over (it will take a while if you have a slow bandwidth) you will be asked to choose a display manager (GDM or KDM-KDE4). Just hit the forward button.

The installation will start and, when it is over, just log out. Then select the ‘KDE 4′ option in the “Select Session” entry of the GNOME login manager. It will log you into the KDE 4.1 . That’s all! And here are some screenshots of KDE 4.1:


Problem Solve:
Some people might have a problem installing this package, it says that it’s trying to write over /usr/lib/kde4/share/doc/kde4/HTML/en/kcontrol/kwindecoration/index.docbook but it can’t.
There’s 2 ways to solve this problem,

You (probably) already have some kde 4 packages installed… so you need to upgrade them first. Try to execute the following command in a terminal:

sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install kubuntu-kde4-desktop

you can solved it by running

sudo gedit kdebase-runtime-data.list
and deleting all lines with /usr/lib/kde4/share/doc/
after that type sudo apt-get -f
It should solve this problem.

That’s all of the current tutorial, hope it will help you to perform the KDE 4.1 installation.
