Ubuntu is pleased to bring you the first set of developer images that capture the current fleeting reality of their Precise Pangolin (Ubuntu 12.04 Alpha 1) as it starts to emerge.
Pre-releases of Precise Pangolin are *not* encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu developers and those who want to help intesting, reporting, and fixing bugs as we work towards getting this LTS release ready.
Alpha 1 is the first in a series of milestone CD images that will be released throughout the Precise development cycle. The Alpha images are known to be reasonably free of showstopper CD build or installer bugs, while representing a very recent snapshot of Precise. You can download them here:
(Ubuntu Desktop, Server, ARM)
Additional images are also available at:
(Ubuntu Server Cloud and EC2)
Alpha 1 includes a number of software updates that are ready for wider testing. This is quite an early set of images, so you should expect some bugs. For a more detailed description of the changes in the Alpha1 release and the known bugs (which can save you the effort of reporting a duplicate bug, or help you find proven workarounds), please see:
If you’re interested in following the changes as we further develop Precise, we suggest that you subscribe initially to the ubuntu-devel-announce list. This is a low-traffic list (a few posts a week) carrying announcements of approved specifications, policy changes, alpha releases, and other interesting events.
