como posso modificar meu endereço MAC para sempre no Ubuntu?

Question

Eu tenho que modificar meu endereço MAC do Ubuntu por algum motivo. através do google, eu escolho editar o arquivo /etc/network/interfaces .

Antes de editar (o conteúdo do arquivo):

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

Depois da edição:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

＃(Way 1)  I have tried to edit these three lines.
#auto enp1s0   
#iface enp1s0 inet static
#hwaddress ether 30:65:EC:32:48:D3

＃(Way 2)  I have tried to edit these two lines ,too.
#auto enp1s0
#iface enp1s0 inet dhcp*

＃(Way 3)
iface enp1s0 inet static
pre-up ifconfig enp1s0 hw ether 30:65:EC:32:48:D3

Mas quando eu reinicio o computador, não consigo encontrar o meu enp1s0.

a saída para ifconfig :

Acho que meu arquivo de configuração estava errado, mas não sei como corrigi-lo.

Alguma sugestão?
