<P> Installing, updating and removing software in Linux is typically done through the use of package managers such as the Synaptic Package Manager, PackageKit, and Yum Extender . While most major Linux distributions have extensive repositories, often containing tens of thousands of packages, not all the software that can run on Linux is available from the official repositories . Alternatively, users can install packages from unofficial repositories, download pre-compiled packages directly from websites, or compile the source code by themselves . All these methods come with different degrees of difficulty; compiling the source code is in general considered a challenging process for new Linux users, but it is hardly needed in modern distributions and is not a method specific to Linux . </P> <Ul> <Li> Samples of graphical desktop interfaces </Li> <Li> <P> Unity </P> </Li> <Li> <P> Cinnamon </P> </Li> <Li> <P> GNOME </P> </Li> <Li> <P> Enlightenment </P> </Li> <Li> <P> KDE Plasma </P> </Li> <Li> <P> LXDE </P> </Li> <Li> <P> LXQt </P> </Li> <Li> <P> Mate </P> </Li> <Li> <P> Pantheon </P> </Li> <Li> <P> Fluxbox </P> </Li> <Li> <P> Sugar </P> </Li> <Li> <P> Trinity </P> </Li> <Li> <P> Xfce </P> </Li> <Li> <P> i3 - gaps </P> </Li> <Li> <P> Budgie </P> </Li> </Ul> <Li> Samples of graphical desktop interfaces </Li> <Li> <P> Unity </P> </Li>
