有时候你可能想知道安装的软件包来自于哪个仓库。这将帮助你在遇到包冲突问题时进行故障排除。因为第三方仓库拥有最新版本的软件包，所以有时候当你试图安装一些包的时候会出现兼容性的问题。在 Linux 上一切都是可能的，因为你可以安装一个即使在你的发行版系统上不能使用的包。你也可以安装一个最新版本的包，即使你的发行版系统仓库还没有这个版本，怎么做到的呢？这就是为什么出现了第三方仓库。它们允许用户从库中安装所有可用的包。

方法-2：使用 yumdb 命令
yumdb info 提供了类似于 yum info 的信息但是它又提供了包校验和数据、类型、用户信息（谁安装的软件包）。从 yum 3.2.26 开始，yum 已经开始在 rpmdatabase 之外存储额外的信息（user 表示软件是用户安装的，dep 表示它是作为依赖项引入的）。
