Debian10Standard版安装network-manager后,用nmcli,nmtui设置网络时,NetworkManager报"Device Not Managed" 221020记录

现象

root@ds10:~# nmcli connection show
NAME      UUID                                  TYPE      DEVICE
nmtui010  c888d2f8-2204-45e6-add5-dbdf53ff8f9d  ethernet  --
root@ds10:~# nmcli connection up nmtui010
Error: Connection activation failed: No suitable device found for this connection (device lo not available because device is strictly unmanaged).

解决办法

查看 /etc/NetworkManager/NetworkManager.conf

sudo cat /etc/NetworkManager/NetworkManager.conf

原先内容

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

打开编辑 /etc/NetworkManager/NetworkManager.conf

sudo vi /etc/NetworkManager/NetworkManager.conf

将 managed=false 改为 managed=true 修改后的内容为

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false
managed=true

👆可以直接将 managed=true 加在 managed=false 下面 重启 NetworkManager

sudo systemctl restart NetworkManager
