Ubuntu 18.04 以太网不受管理

我在 Ubuntu 18.04 上遇到了以太网不受管理的问题。虽然互联网工作正常，但这让我无法设置 vino 屏幕共享。

以下是一些输出：

superuser@SuperTower:~$ nmcli d

superuser@SuperTower:~$ cat /etc/network/interfaces

iface lo inet loopback


superuser@SuperTower:~$ cat /etc/NetworkManager/NetworkManager.conf 
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[device]
wifi.scan-rand-mac-address=no


superuser@SuperTower:~$ ls -al /etc/NetworkManager/conf.d/10-globally-managed-devices.conf

superuser@SuperTower:~$ cat /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf

unmanaged-devices=none



superuser@SuperTower:~$ cat /etc/netplan/01-network-manager-all.yaml 
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

我已经尝试过这里各种问题的解决方案，并且

superuser@SuperTower:~$ sudo nmcli dev set eno1 managed yes

但没有任何帮助。仍然没有得到管理。有什么想法吗？

这似乎产生了魔力：

superuser@SuperTower:~$ cat /etc/NetworkManager/NetworkManager.conf 
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[device]
wifi.scan-rand-mac-address=no


superuser@SuperTower:~$ cat /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf
[keyfile]
unmanaged-devices=*,except:type:wifi,except:type:wwan


superuser@SuperTower:~$ cat /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
[keyfile]
unmanaged-devices=none

另外，仅重新启动网络管理器服务也无济于事。只有完全重启。
