各位 Debian 用户大家好，
我最近购买了一个戴尔 Optiplex 790，安装了 Debian 10.9 并放置了ATI蓝宝石卡在里面。需要驱动程序来修复显示尺寸变化时的屏幕变色，我添加了FGLRX 专有驱动程序。现在我需要设置一些应用程序，例如 OBS studio，但我似乎找不到它们突触。我尝试手动下载 deb 文件进行安装，但是依赖项与核心包冲突。我想要让 synaptic 恢复拥有完整的主 Debian 存储库包。我怎么做？
Aptitude 源的输出：

您的源中缺少主存储库。
您至少需要添加
deb http://deb.debian.org/debian buster main
查看/etc/apt/sources.list示例sources.list）并重新加载包索引
sudo apt update
在终端中或Ctrl + R在 synaptic 中选择“重新加载包信息”( )。
