Daily builds of Ubuntu 12.04 LTS (Precise Pangolin) are now available
Desktop CDUbuntu 12.04 LTS (Precise Pangolin) Daily Build available
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 384MiB of RAM to install from this CD.
There are two 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.
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.
