我正在运行 12.10 的原始安装。所有网络设置的 UI 都呈灰色，例如，如果我右键单击右上方栏图标或转到系统设置 -> 网络 -> 选项（所有选项都呈灰色）。
连接被标记为“可供所有用户使用”，所以我猜测需要权限才能更改设置。
这很好，但是我如何使用这些权限访问 UI？
我可以通过 sudo 启动设置菜单，但不知道该命令。

答案1
您是否编辑过 /etc/network/interfaces？如果您手动配置，或者程序进行了配置，网络管理器将无法管理它们。例如...这是我让网络管理器处理的...

iface lo inet loopback
如果你有一条分配 IP 和其他内容的线路，那么你就是在控制它，本质上是在告诉网络管理员不要乱动它
