Believe it or not, the UCP curriculum suggests that you need to know the history of Ubuntu releases. It explicitly cites names such as Warty Warthog and Dapper Drake. So let's review what's been released by Canonical, the corporate sponsor created by Mark Shuttleworth for the Ubuntu distribution. First, there are 3 GUI based builds released by Canonical, Ubuntu Linux includes the Gnome Desktop environment. Kubuntu Linux is designed for the KDE Desktop environment. And Xubuntu Linux is customized for the Xfce Desktop environment. There are also other releases from Canonical, Ubuntu Server includes a customized server Kernel and no default GUI. Ubuntu JeOS is designed for virtual machines. Yes, there are more Canonical releases, Goubuntu Linux is a Gnome based version of Ubuntu that's limited to open source software. Ubuntu Studio is designed for users who need multimedia applications. MP Linux is a variant of Ubuntu, released by a company also owned by Mark Shuttleworth. So strictly speaking it's not a Canonical release. Canonical, the corporate sponsor of Ubuntu releases each of these variants on a 6 month cycle. Each release includes a 2 word codename and a version number. The version number is associated with the release month and year. For example, the version number associated with the Hardy Heron release is 8.04. In other words, it was released in the year 2008 in the 4th month. I'll give you a few moments to review the following screens which list releases and their codenames. Read them carefully, as these codenames are explicitly cited in the curriculum and are therefore fair game on the exam. The LTS next to Dapper Drake and Hardy Heron stand for Long Term Support. In other words, Canonical supports these releases for 3 years on the Desktop and 5 years on the server. Finally, there are the other releases based on Ubuntu Linux, also known as derivatives. Some of these derivatives include Freespire released by the company formerly known as Lindows and Mythbuntu which incorporates the Myth TV applications for digital multimedia. Those are just a couple of examples. There are over a dozen other variants but to identify the operating system that you work with, you'll need to be able to confirm the current release. It's documented in the ETC/LSB--release file. Or it can also be found in the output, the LSB release command as shown here. We have the contents of the etc/LSB release file and the output to the LSB release---8 command, which confirms that we're working with the Hardy Heron release. Thank you, and on to the following video.
