With all the hoopla and excitement today in regards to KDE 4.0 release I thought I would publish some instructions on installation for those that want to try it out. There is a KDE 4.0 LiveCD available if you’d like to “try before you buy”, and this tutorial will install KDE 4.0 alongside your current installation so you should still be able to revert if you run into problems.
Installing KDE 4.0
First of all we need to update the repository sources list to pull these new KDE 4.0 packages from the kubuntu team PPA (Personal Package Archive). We do that by editing the /etc/apt/sources.list file:
sudo vim /etc/apt/sources.list
You’ll want to then append this line:
deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu gutsy main
(The above should be on one line.) We’re now ready to install the KDE 4.0 packages:
sudo aptitude update
sudo aptitude install kde4-core
Removing Previous KDE 4.0 Releases
note: do make sure you remove any previous KDE 4.0 installations you may have been playing with. The previous packages can have conflicts with this newer release from the PPA.
To remove previous KDE 4.0 packages, use the command:
sudo aptitude remove kdelibs5 kde4base-data kde4libs-data
You can now launch your newly added KDE 4.0 environment from the login manager by selecting KDE 4. Enjoy!
