Почему Certbot не находит плагин под NGINX?

Выполняю команду: sudo certbot --nginx

Выдает:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
The requested nginx plugin does not appear to be installed

В 16.04 нет пакета python-certbot-nginx поэтому все делаем руками.

## Ставим CertBot
sudo apt-get install certbot

## Создаем папку
sudo mkdir -p /var/www/cert_bot/.well-known/acme-challenge
sudo chown -R www-data:www-data /var/www/cert_bot

## Создаем базовый конфиг в /etc/nginx/site-enable/default 
server {
          listen  80;
          
          server_name  _;
        root /var/www/cert_bot;

        location /.well-known/acme-challenge/ {
                access_log off;
                default_type "text/plain";
        }
        location / {
                return 301 https://$server_name$request_uri;
                }
}

## Пробуем запросить сертификат
sudo certbot certonly --dry-run--webroot --agree-tos --email hostmaster@domain.com -w /var/www/cert_bot/ -d domain.com 

## Если все ок, заправиваем без --dry-run
sudo certbot certonly --webroot --agree-tos --email hostmaster@domain.com -w /var/www/cert_bot/ -d domain.com 

## Добавляем конфиг с SSL /etc/nginx/site-enable/domain-ssl
server {
        listen   443 ssl;
       
        server_name domain.com;
        

        ssl                  on;
        ssl_stapling on;
        ssl_stapling_verify on;
        ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/domain.com/privkey.pem;
        #ssl_dhparam /etc/nginx/dhparam.pem;

        root /var/www/html
}

## Добавляем в крон автообновление сертификата 
sudo crontab -e -u root
0 0 10,25 * * certbot renew

Почему Certbot не находит плагин под NGINX?

Потому что актуальная версия Убунты - 22, а у вас 16. Обновитесь.
