January 27, 2009. The KDE Community announced the immediate availability of "The Answer", (a.k.a KDE 4.2.0), readying the Free Desktop for end users. KDE 4.2 builds on the technology introduced with KDE 4.0 in January 2008. After the release of KDE 4.1, which was aimed at casual users, the KDE Community is now confident we have a compelling offering for the majority of end users.

If you want to know about the changes check here

Install KDE 4.2 in Ubuntu 8.10

Note:-  If you installed KDE 4.2 Beta or RC you can merely update your existing installation using the following commands

sudo apt-get update

sudo apt-get dist-upgrade

If you are installing first time follow this procedure

First Remove the koffice-data-kde4 package if you have it installed. The current koffice2 packages in the kubuntu-members-kde4 PPA are incompatible with the KDE 4.2 packages since they try to install icons to the same locations.

Now you need to edit the sources.list file using the following command

sudo gedit /etc/apt/sources.list

add the following line

deb http://ppa.launchpad.net/kubuntu-experimental/ubuntu intrepid main

Save and Exit the file

You can add the package signing key with this command

gpg --keyserver keyserver.ubuntu.com --recv-keys 493B3065 && gpg --export -a 493B3065 | sudo apt-key add -

Update the source list using the following command

sudo apt-get update

Install kubuntu desktop package using the following command

sudo apt-get install kubuntu-desktop

or

install only kde4 packages

This will complete the installation.

Now log out and press Alt + E to restart X. When you log in you will have KDE 4.2.

Important Notes

  • KDE 4.2 uses Akonadi which will install MySQL. The MySQL packages in intrepid will ask for a password, you can set this to anything you like.
  • Digikam will not install alongside these packages due to conflicting library versions.
  • Old Plasma packages are not compatible with KDE 4.2, you should uninstall any plasmoids.

    Would be nice if you also published a guide how to install KDE 4.2 alongside Gnome, without doing the whole kubuntu-desktop thing.

    I cant access the network if I go directly into the kde environment. I first need to go to gnome and then after that go to kde. Its just annoying.

    Hmmm I followed all your instructions and yet I only got kde 4.1.4 to install instead of 4.2, and kde seems to be slower than gnome on my system.

    Same here, it only took me up to 4.1. I did see it install a few packages from the launchpad.net repository, so I know I added the repository okay.

    Followed these instructions — took me to 4.1 on my 32-bit system, 4.2 on my 64-bit system.

    When I finished I rebooted. The login screen was different and them emblem was KDE, but the Gnome desktop was back once it fully booted.

    I am doing a remove of KDE-desktop and auto-remove. What else need I do?

    I had the same problem that kde was not updated to version 4.2.
    Now I just saw on the kde website that they changed the way you should get the update:
    instead of including the above repository you should now activate unsupported updates. After having done this, everything worked fine.

    Well, I followed these directions and regret doing so. KDE 4.2 does *not* work; KDM starts ok, but I get constant failures from kstartupconfig4 and the KDE desktop never starts. Searching, I fixed one only to get another. Uninstalling leaves a bunch of cruft on my desktop menus. Fortunately, I think I’ve restored things to a proper state.

    No one to blame but myself; I had a feeling I should not have tried this. Beware…
