[5.715564] e1000 0000:02:01.0 eth0: (PCI:66MHz:32-bit) 00:0c:29:7d:bf:43
    [5.715573] e1000 0000:02:01.0 eth0: Intel(R) PRO/1000 Network Connection
    [5.719709] e1000 0000:02:01.0 ens33: renamed from eth0複製代碼

and we get ens33 renamed from eth0, we need to change it back to eth0.

#GRUB_CMDLINE_LINUX=""
    GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"複製代碼

$ sudo update-grub複製代碼

(2) edit network interfaces

auto lo
    iface lo inet loopback複製代碼

auto eth0
    iface eth0 inet static
    address 192.168.1.77 
    netmask 255.255.255.0
    gateway 192.168.1.1 複製代碼

(3) reboot

sudo reboot now複製代碼

(4) check eth0

$ sudo ifconfig複製代碼
