I have error secure apache on Digital Ocean?

Hello,
I want to set https for my hosting on ubuntu 18 under Digital Ocean as it is written here:
https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04

But I had problems with ufw settings:

# sudo ufw status
Status: inactive
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw allow 'Apache'
Rules updated
Rules updated (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status

I see that status is inactive.


I tried to make :

# sudo ufw app list
Available applications:
Apache
Apache Full
Apache Secure
OpenSSH

I think this error is critical and did not proceed with next commands. Why error and how to fix it ?

Thanks!
