Ubuntu 16.04 全新安装，无互联网（以太网）

我在 Windows 10 旁边安装了全新的 Ubuntu。在 Windows 中，我可以通过以太网访问互联网。在 Ubuntu 中，我可以看到有线连接 1，但没有互联网访问。我位于本地网络后面。

Ubuntu 16.04.6 LTS

以下是一些命令的结果：

是否配置

sudo lshw -C 网络

sudo gedit /etc/NetworkManager/NetworkManager.conf

sudo gedit /etc/network/interfaces

我尝试将接口设置为：

auto enp0s31f6
iface enp0s31f6 inet auto

然后重新启动网络管理器/重启，但不起作用。事实上，一旦重新启动，enp0s31f6 接口就不会显示在 ifconfig 中。任何帮助都非常感谢，谢谢。

编辑：通过 USB 网络共享，正常网络连接

尝试了 sudo apt-get update、sudo apt-get upgrade，仍然没有通过以太网连接互联网
