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
