It support 64bit machines only. The Ubuntu team is very pleased to announce the release of Ubuntu 12.04.1 LTS (Long-Term Support) for desktop, server, cloud and core products. The Ubuntu LTS flavors are also being released today. In the 12.04.1 release, we've added support for the Calxeda ECX-1000 SoC family, so businesses can prepare for a data centre dominated by low-energy, hyperscale servers by testing their workloads on the new hardware now. The Ubuntu Cloud archive also makes its début.
 
About Ubuntu
Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customise and alter their software in whatever way they see fit. "Ubuntu" is an ancient African word, meaning "humanity to others". The Ubuntu distribution brings the spirit of Ubuntu to the software world.
