Невозможно разрешить Nginx в брандмауэре

Я установил Nginx на свой сервер Ubuntu 18.04 с помощью следующей команды:

$ sudo apt-add-repository ppa:hda-me/nginx-stable

$ sudo apt update

$ ubuntu@www-example-com:~$ sudo apt install brotli nginx nginx-module-brotli

The Brotli dynamic module for nginx has been installed.
To enable this module, add the following to /etc/nginx/nginx.conf
and reload nginx:
    # ngx_brotli filter module - used to compress responses on-the-fly.
    load_module modules/ngx_http_brotli_filter_module.so;
    # ngx_brotli static module - used to serve pre-compressed files.
    # Both modules could be used separately
    load_module modules/ngx_http_brotli_static_module.so;

Please refer to the module documentation for further details:
https://github.com/google/ngx_brotli

Моя проблема в том, что мне невозможно добавить Nginx в свой брандмауэр с помощью следующей команды. Не понимаю, почему не работает:

$ ubuntu@www-example-com:~$ sudo ufw allow 'Nginx Full'
ERROR: Could not find a profile matching 'Nginx Full'

$ ubuntu@www-example-com:~$ sudo ufw app list
