Ricordo che la versione alpha è la versione di sviluppo di Ubuntu, che diventerà in seguito stabile.
Quindi non utilizzatela per un uso quotidiano, in quanto potenzialmente soggetta a bug critici che potrebbero portare anche alla perdita di dati.
Qui c’è l’annuncio:
Hello Ubuntu developers,
Welcome to Karmic Koala Alpha 4, which will in time become Ubuntu 9.10.
Pre-releases of Karmic 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 4 is the fourth in a series of milestone CD images that will be
released throughout the Karmic 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 Karmic. You can download it here:
http://uec-images.ubuntu.com/releases/karmic/alpha-4/ (Ubuntu Server UEC)
http://cdimage.ubuntu.com/ubuntustudio/releases/karmic/alpha-4 (Ubuntu Studio)
See http://wiki.ubuntu.com/Mirrors for a list of mirrors.
Alpha 4 introduces the first Ubuntu Enterprise Cloud alpha images for
Karmic. Information on using these images on your UEC instance or on Amazon
EC2 can be found at the download page at:
Alpha 4 also includes a number of software updates that are ready for
large-scale testing. Please refer to
http://www.ubuntu.com/testing/karmic/alpha4 for information on changes in
This is quite an early set of images, so you should expect some bugs. For a
list of known bugs (that you don’t need to report if you encounter), please

Karmic, have a look at the karmic-changes mailing list:
We also suggest that you subscribe to the ubuntu-devel-announce list

low-traffic list (a few posts a week) carrying announcements of
