[Warning! Old Article that was moved!] If you're eager to get KDE 4.2 installed on your (K)Ubuntu system
now before Jaunty is released, just follow this quick, complete guide.
This is good for various releases of Ubuntu. I am currently running
the Alpha release of Jaunty on 32 and 64 bit systems and still
correctly upgraded to KDE 4.2. This guide is meant to be extremely
fast so there's little mouse clicking here, just the command line. Open the terminal and type/insert the command to edit your sources list: sudo gedit /etc/apt/sources.list Add
the following line to the end of your sources list. This will add the
reposititory to install KDE. Where [your version] is please replace
with the appropriate name: jaunty, intrepid, hard, et cetera. deb http://ppa.launchpad.net/project-neon/ubuntu [your version] main Add the key to access the repo gpg --keyserver keyserver.ubuntu.com --recv-keys 493B3065 && gpg --export -a 493B3065 | sudo apt-key add -Update your packages... sudo aptitude update Then install KDE! sudo aptitude install kubuntu-desktop |
