KDE 4.3 is out! Great, but there is no official support for Ubuntu 9.04 (Ubuntu’s next release due in October will) so how can I install KDE 4.3?

First, add the following repositories

sudo sh -c "echo 'deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu jaunty main' >> /etc/apt/sources.list"
sudo sh -c "echo 'deb http://ppa.launchpad.net/kubuntu-ppa/staging/ubuntu jaunty main' >> /etc/apt/sources.list"

and the gpg key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8AC93F7A

Now you can install KDE 4.3 with

sudo apt-get install kubuntu-desktop

Sounds easy – but the kubuntu-docs package won’t install

Setting up kubuntu-docs (9.04.2) ...
ln: target `/usr/share/doc/kde/HTML/en/kubuntu/' is not a directory: No such file or directory
dpkg: error processing kubuntu-docs (--configure):
subprocess post-installation script returned error exit status 1

After googling for a while I found a bugreport (with a fix) here.

Steps are:

1) Run “sudo apt-get install kubuntu-desktop”
2) Apply the patch: download “fix_kubuntu_docs.patch“  and run “sudo patch -p0 < fix_kubuntu_docs.patch”
3) Run “sudo apt-get install kubuntu-docs”
