Kubuntu 10.04 LTS RC
Kubuntu is a user friendly operating system based on KDE, the K Desktop Environment. With a predictable 6 month release cycle and part of the Ubuntu project, Kubuntu is the GNU/Linux distribution for everyone.
The Kubuntu CDs are made up of Ubuntu’s base plus KDE. You can get exactly the same effect by installing Ubuntu and adding the KDE packages (and removing the Gnome packages) from the Ubuntu archives.
Kubuntu CD and DVD ISOs are available for PCs (i386), Mac (PowerPC) and 64-bit PCs (AMD64).
Both live (runs off the CD) and install versions are available. The DVDs are combined live and install.
