Cek ip server : 

ip a

akan tampil seperti ini : (CONTOH)
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
      valid_lft forever preferred_lft forever
   inet6 ::1/128 scope host 
      valid_lft forever preferred_lft forever
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
   link/ether 00:1d:97:b5:fa:08 brd ff:ff:ff:ff:ff:ff
   inet 10.10.10.123/24 brd 10.10.10.255 scope global dynamic enp1s0
      valid_lft 429sec preferred_lft 429sec
   inet6 fe80::21d:97ff:feb5:fa08/64 scope link 
      valid_lft forever preferred_lft forever

Terlihat bahwa adapter yang digunakan adalah enp1s0 dengan ip dinamis 10.10.10.123 (untuk pc/server lain mungkin akan berbeda adapter dan ip-nya).

Command lain seperti 

ifconfig -a

Masuk ke netplan 

cd /etc/netplan

ls

edit file yaml, contoh 00-installer-config.yaml 

sudo nano 00-installer-config.yaml

isinya seperti berikut ini : 

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp1s0:
      dhcp4: true
  version: 2

rubah menjadi :
