I have error secure apache on Digital Ocean?

[mstdmstdd]

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
Status: inactive
root@nsn-do-lamp:/etc/apache2/sites-available# sudo systemctl reload apache2
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status
Status: inactive
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw allow 'Apache Full'
Skipping adding existing rule
Skipping adding existing rule (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw delete allow 'Apache'
Rules updated
Rules updated (v6)
root@nsn-do-lamp:/etc/apache2/sites-available# sudo ufw status
Status: inactive

I see that status is inactive.


I tried to make :

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

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

Thanks!

Is UFW enabled? Do you even need UFW enabled?

Thank you!
Command 

sudo ufw enable

was helpfull

But next I was asked :

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.
 

I suppose I have to select point 2) I want to set to my https site, but the thing is that I gave the url of my site
with http protocol. Could it be a problem with old url?

As long as you don't have any <form method=POST>s pointing to a http:// URL then you're okay because it will redirect. But you should avoid those redirects whenever possible, ie. any URL you construct needs to say https://.
