Using a LiveCD

Installing 4.9 beta 1 with your distribution packages
There is a dedicated [kde-unstable] repository. This repo only contains KDE/Calligra beta and RC releases (with their unstable deps); when the stable version is out, the packages are moved to the [extra] repository.
Installation steps are at:
In case you want to test Pairs alone, you can use the package from aur 'pairs-git': http://aur.archlinux.org/packages.php?ID=56310
Provides scm versions (ebuilds) for master/trunk & stable branch, betas and rc's in an extra repository (overlay). Detailed install instructions can be found here:
There is an unofficial kde-unstable/kde-testing and a kde-stable repo maintained by Rex Dieter - the place where the newest bits come for already released stuff. But Fedora Rawhide is always the first place for all builds.
Packages for Kubuntu Utopic For Utopic (14.10) releases of KDE Frameworks 5 and Plasma 5 are being packaged in the next PPA. These will replace your Plasma 4 install.
sudo apt-add-repository ppa:kubuntu-ppa/next sudo apt update sudo apt install kubuntu-plasma5-desktop sudo apt full-upgrade sudo reboot [save any work first; sorry no elegant way to reboot]
For daily builds, install ppa:kubuntu-ci/unstable as above.
Live Images of Utopic Kubuntu Plasma 5 images are a development build of what will become the default desktop for Kubuntu next year.

Compiling the sources
Compiling a single application against your KDE 4.8 installation
You need the Qt (>= 4.7) and kdelibs (4.8) development packages. Then follow:
Build-tool is a ruby program which will build the 4.9 beta 1 packages. It also has some neat features like progress bars and eta for compile time. It can also automatically generate a ~/.xsessionrc which can be used by KDM when you select to boot into a "Custom" session type. That will enable you to easily get into a KDE session which was built from source, without even having to modify any of your scripts like ~/.bashrc, ~/.zshrc, etc.
Install ruby 1.9 and rubygems through your package manager. Run 'sudo gem install build-tool'. Now that build-tool is installed, we need to install the KDE recipes to have it build KDE from source. Run 'build-tool recipe add git://gitorious.org/build-tool/kde-trunk-recipe.git kde' to add the KDE recipe to the program. Then 'build-tool recipes install kde'. From there, you can run 'kde-build help' to see the commands available for the KDE recipe, as well as compile and update the git repositories.
