Welcome to Lucid Lynx Alpha 1, which will in time become Ubuntu 10.04 LTS.
Pre-releases of Lucid 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 in testing, reporting, and fixing bugs.
Alpha 1 is the first in a series of milestone CD images that will be
released throughout the Lucid 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 Lucid. You can download it here:
