Selecting the Ubuntu Version

Each Ubuntu release is designed to require only one CD-ROM for installing the system. This reduces the need for swapping disks during the installation. Unfortunately, one disk cannot hold everything needed for a complete environment. To resolve this issue, Ubuntu has many different types of initial install images that address different system needs.

Desktop—This image provides a Live Desktop. This can be used to test-drive the operating system or install a desktop or workstation system. The installation includes the Gnome graphical environment and user-oriented tools, including office applications, multimedia players, and games.

Alternate—Similar to the Desktop image, this image installs the desktop version of Ubuntu, but it does not use a graphical installer. This is a very desirable option when the graphics or mouse does not work correctly from the Desktop installer.

Server—This minimal install image has no graphical desktop. It is ideal for servers and headless (without monitor) systems. The image includes server software such as a Secure Shell server,web server, and mail server, but none is installed by default.

Netbook—Introduced with Jaunty Jackalope (9.04), the netbook edition (also called the Ubuntu Netbook Remix) is a version customized for portable netbook systems.

The names for the installation images do not exactly match the functionality. The names were chosen to avoid confusion with previous Ubuntu releases. (If they called the Desktop CD-ROM Install, people might not realize it also contains a Live Desktop.) Better names might be Live CDwith Desktop Install, OEMwith Text Desktops, and Server with Minimal System Configuration. But then again, these are pretty long names, so we’ll stick with Desktop, Alternate, Server, and Netbook.

There are more installation options than these four CD-ROM images. For example, there is an Ubuntu DVD image. The DVD contains everything found on all of the CD-ROM images, including the live operating system. There are also unofficial ports to other platforms. For example, installation disks for the PowerPC, Sun UltraSPARC, IA-64, and other architectures are available from While these platforms may not receive immediate updates and first-tier support, they are community supported.

Each installation disk has the option for a basic install as well as a few other common options. For example, you can verify the installation media using the check for CD defects, test your hardware with the Memory Test, and access an installed system using the Rescue option. There are also options specific to certain installation disks.

From the Ubuntu web site (, it can be difficult to find anything other than the Desktop and Server versions of the current and LTS releases for download. The web sites and provide easy access to all of the release images.
