Ubuntu Linux Distributions

Ubuntu is probably the most well-known distribution of GNU/Linux. It is popular on desktop computers as well as on servers. It is based on Debian, although it is not fully compatible with it because of various modifications. Ubuntu also serves as a base for numerous other Linux distributions. Ubuntu is known for developing their Ubuntu-specific features instead of extending the work already done by other Linux distributions.
