What is Kubuntu?
The Kubuntu distribution is a spin-off from Ubuntu, which aims to create a new user-friendly desktop system using the Linux operating system. Kubuntu comes with the KDE Plasma Desktop Environment installed by default and provides users with similar functionality and visual appearance (a 'look-and-feel') to other current popular operating systems such as Windows XP and Apple's Mac OS X.
What is Opkg?
Opkg is the package management system used on embedded Linux systems, most notably OpenWrt. It was designed to replace the Rpm Package Manager (RPM), Debain packages, Alien packages, and the Red Hat Package Manager (RPM), but it can be used with any Linux distribution. With opkg you can easily download and install software packages from the Internet to keep your router up to date without a lot of hassle.
