處理前動作

檢查文件中已經有配置: /etc/network/interfaces 如果有需要註解，範例如下:

# The primary network interface
# allow-hotplug enp1s0
# iface enp1s0 inet dhcp

新增網卡配置

sudo nmcli connection add type ethernet con-name enp1s0 ifname enp1s0 ipv4.addresses 192.168.56.100/24 gw4 192.168.56.1 ipv4.dns 127.0.0.1  ipv4.method manual

設定完需要重起 NetworkManager

sudo systemctl restart NetworkManager
