This alpha features images for Kubuntu, Lubuntu, Ubuntu GNOME, UbuntuKylin and the Ubuntu Cloud images.
Pre-releases of the Vivid Vervet 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 flavor developers and those who want to help in testing, reporting and fixing bugs as we work towards getting this release ready.
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.
While these Alpha 1 images have been tested and work, except as noted in the release notes, Ubuntu developers are continuing to improve the Vivid Vervet. In particular, once newer daily images are available, system installation bugs identified in the Alpha 1 installer should be verified against the current daily image before being reported in Launchpad. Using an obsolete image to re-report bugs that have already been fixed wastes your time and the time of developers who are busy trying to make 15.04 the best Ubuntu release yet. Always ensure your system is up to date before reporting bugs.
Ubuntu GNOME Alpha Releases are recommended for:
- Regular users who want to help us test by finding, reporting, and/or fixing bugs
- Ubuntu GNOME developers
For those who don't know the general difference between Alpha and Beta:
- With Alpha releases, we don't introduce many new features. The system that you are testing on the Alpha stage is under heavy development, however there is a a great chance you will not notice anything just yet.
- It is very common to see -- for example -- the slide show of the installer states you are installing 14.10 not 15.04. That's not a real bug when it is Alpha. It would be a bug if we are at Beta.
- You usually start to see some visible differences with Beta but not Alpha.
