sudo ufw enable
sudo ufw default deny

And I then do:

sudo iptables -L

All I needed was:

$ sudo ufw enable

I then got the following prompt:

Command may disrupt existing ssh connections. Proceed with operation (y|n)?

After hitting “y” I saw:

Firewall is active and enabled on system startup

And sudo ufw status gave me the expected output.

Well this might be quite old to reply but do remember to add sudo ufw allow 22/tcp otherwise you will not be able to do ssh into your vm once you exit out of it.
