以太网连接不稳定

我的 Ubuntu 19.10 64 位以太网连接不稳定。问题与以太网不稳定 - Ubuntu 13.10，仍未解决。我在 Windows 上没有遇到同样的问题。

通过日志记录我发现我的连接此时中断了：

device (ppp0): state change: disconnected -> unmanaged (reason 'connection-assumed', sys-iface-state: 'external')
manager: (ppp0): new Ppp device (/org/freedesktop/NetworkManager/Devices/9)
device (ppp0): state change: unmanaged -> unavailable (reason 'connection-assumed', sys-iface-state: 'external')
device (ppp0): state change: unavailable -> disconnected (reason 'none', sys-iface-state: 'external')

答案1

修复 .yaml 文件似乎已经解决了该问题（18.04 服务器，以太网接口通过 lspci 可见，但 lshw -C 网络缺失）。我将 enp0s7 更改为 enp0s10，并按照答案编辑文件
