其他软件库

In addition to the officially supported package repositories available for Ubuntu, there exist additional community-maintained repositories which add thousands more potential packages for installation. Two of the most popular are the Universe and Multiverse repositories. These repositories are not officially supported by Ubuntu, but because they are maintained by the community they generally provide packages which are safe for use with your Ubuntu computer.

[注意]

Multiverse 软件库中的软件包通常有授权问题,这阻碍了它们随同一个自由操作系统一起发布,并且它们在您所处的地域中可能是非法的。

[警告]

提醒您在 UniverseMultiverse 软件库中均没有官方支持的软件包。特别是这些软件包可能没有安全更新。

许多其他软件包源也是可用的,有时甚至只提供一个软件包,这种情况主要发生在由单个应用程序的开发人员所提供软件包源上。然而当您在使用非标准软件包源时您应该非常小心谨慎,在执行任何安装之前仔细考查源和软件包,因为有些软件包源和其中的软件包可能会使您的系统在某些方面运行不稳定或不正常。

Starting Gutsy Gibbon, by default, the Universe and Multiverse repositories are enabled. But if you have disabled them, add or edit the /etc/apt/sources.list file and uncomment the following lines to enable those repositories:

deb http://archive.ubuntu.com/ubuntu feisty universe multiverse
deb-src http://archive.ubuntu.com/ubuntu feisty universe multiverse
