UbuntuLinux是一份完整的桌面Linux操作系統(tǒng)，它可免費獲得，并帶有社團(tuán)及專業(yè)的支持。Ubuntu社團(tuán)按照Ubuntu宣言里所銘記的思想而組建：軟件應(yīng)免費提供，軟件工具應(yīng)能以人們本地語種的形式可用且不犧牲任何功能，人們應(yīng)擁有定制及改變他們軟件的自由，這包括以任何他們認(rèn)為適宜的方式。Ubuntu是一個古非洲語單詞，意指對他人的博愛。Ubuntu Linux發(fā)行將這種博愛之心帶到了軟件的世界中。

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 notesare almost exactly the same as for alpha 5. The only difference is thenumber of known issues - with alpha 6, two of the seven known issueshave been resolved, including the bug where the installer fails to tellthe kernel to reload the partition table during partitioning and theOEM configuration failure. But the "encrypted home directory" featurein the installer is still disabled and the new X.Org Server 1.6 stilldoesn't support the proprietary ATI driver. If you are still interestedin 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).
