Ubuntu 12.04.2 LTS (amd 64bit)
Ubuntu is a community developed operating system that is perfect for laptops, desktops and servers. Whether you use it at home, at school or at work Ubuntu contains all the applications you'll ever need, from word processing and email applications, to web server software and programming tools. Ubuntu is and always will be free of charge. You do not pay any licensing fees. You can download, use and share Ubuntu with your friends, family, school or business for absolutely nothing.
We issue a new desktop and server release every six months. That means you'll always have the latest and greatest applications that the open source world has to offer. Ubuntu is designed with security in mind. You get free security updates for at least 18 months on the desktop and server. With the Long Term Support (LTS) version you get three years support on the desktop, and five years on the server. There is no extra fee for the LTS version, we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge. Everything you need comes on one CD, providing a complete working environment. Additional software is available online. The graphical installer enables you to get up and running quickly and easily. A standard installation should take less than 25 minutes. Once installed your system is immediately ready-to-use. On the desktop you have a full set of productivity, internet, drawing and graphics applications, and games.
To help support a broader range of hardware, the 12.04.2 release adds an updated kernel and X stack for new installations on x86 architectures, and matches the ability of 12.10 to install on systems using UEFI firmware with Secure Boot enabled. As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation.
