The Ubuntu 11.04 Release by Today

Canonical today announced the release of Ubuntu a fast-growing open-source operating system on April 28, 2011 for public download.  Ubuntu 11.04 stands out from its competitors as a genuine free alternative to Windows, allowing users to personalise their PC with free and paid apps in a way that’s proven hugely popular in the smartphone and tablet market.

“This release breaks new ground for Ubuntu by offering users a PC experience that is stylish and efficient” said Jane Silber, CEO of Canonical.  “With this release Ubuntu will recruit an entirely new wave of users to free software. Ubuntu 11.04 is a high watermark for what has been achieved with open-source technologies for the everyday computer user.”

Desktop CD

The desktop CD allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of CD is what most people will want to use. You will need at least 256MiB of RAM to install from this CD.

There are four images available, each for a different type of computer:

PC (Intel x86) desktop CD

For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.

64-bit PC (AMD64) desktop CD

Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.

64-bit Mac (AMD64) desktop CD

Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead. This image is adjusted to work properly on Mac systems.

Mac (PowerPC) and IBM-PPC (POWER5) desktop CD

For Apple Macintosh G3, G4, and G5 computers, including iBooks and PowerBooks as well as IBM OpenPower machines.

Warning: This image is oversized (which is a bug) and will not fit onto a standard 700MiB CD. However, you may still test it using a DVD, a USB drive, or a virtual machine.

A full list of available files can be found below.

If you need help burning these images to disk, see the CD Burning Guide.
