cat /etc/network/interfaces No such file or directory

Question

I just installed Ubuntu Server 20.04.3 in a VMware virtual machine. Now I am not able to use this command:

cat /etc/network/interfaces

as I am not able to see any network interfaces:

No such file or directory

How should I edit my /etc/network/interfaces and assign an IP?

Does this answer your question? What's the default /etc/network/interfaces? — Error404, Jan 08 '22 at 08:41
The method /etc/network/interfaces is long since deprecated. Please check here: https://askubuntu.com/questions/976464/why-is-the-network-configuration-i-set-in-etc-network-interfaces-ignored-on-ubu/976497#976497 Possibly a duplicate. — chili555, Jan 08 '22 at 14:21
Use netplan. Edit your question and show me sudo lshw -C network and cat /etc/netplan/*.yaml. Start comments to me with @heynnema or I'll miss them. — heynnema, Jan 08 '22 at 16:38

Since version 18.04 Ubuntu by default uses netplan to configure network.

Go to /etc/netplan, here you will find your network configuration.

It will look something like this:

00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens18:
      dhcp4: true
  version: 2
