Ubuntu 9.04 刚刚发布第六个 Alpha 测试版本，这也是9.04 版本的最后一个Alpha测试版本。
没有更多的关于 Alpha 6 的发布信息，跟 Alpha 5 几乎一样，唯一不同的是修复了一些bug，其中包括对 ATI 显卡支持的bug等。
Steve Langasek has announced the availability of the sixth and final alpha release of Ubuntu 9.04: "Welcome to Jaunty Jackalope Alpha 6, which will in time become Ubuntu 9.04." Not much information is available on this release; in fact, both the release announcement and release notes are almost exactly the same as for alpha 5. The only difference is the number of known issues - with alpha 6, two of the seven known issues have been resolved, including the bug where the installer fails to tell the kernel to reload the partition table during partitioning and the OEM configuration failure. But the "encrypted home directory" feature in the installer is still disabled and the new X.Org Server 1.6 still doesn't support the proprietary ATI driver. If you are still interested in testing the new release, download (MD5) the live CD images from here: jaunty-desktop-i386.iso (698MB, torrent), jaunty-desktop-amd64.iso (693MB, torrent). The other members of the Ubuntu family have also entered alpha 6: Kubuntu (release notes, download), Xubuntu (download), Ubuntu Studio (download) and Mythbuntu (download).
