Issue using certbot with nginx

I'm actually working on a webapp, I use Reactjs for the frontend and Golang for the backend. Those 2 programs are hosted separately on 2 VMs on Google-Compute-Engine. I want to serve my app through https so I choose to use Nginx for serving the frontend in production. Firstly I made my config file for Nginx:

#version: nginx/1.14.0 (ubuntu)server {     listen 80 default_server;     listen [::]:80 default_server;     root /var/www/banshee;     server_name XX.XXX.XX.XXX; #public IP of my frontend VM     index index.html;     location / {       try_files $uri /index.html =404;     }   }

For this part everything works as expected but after that I want to serve my App over https following this tutorial. I installed the packages software-properties-common,python-certbot-apache and certbot but when I tried

sudo cerbot --nginx certonly

I get the following message:

gdes@frontend:/etc/nginx$ sudo certbot --nginx certonlySaving debug log to /var/log/letsencrypt/letsencrypt.logCould not choose appropriate plugin: The requested nginx plugin does not appear to be installedThe requested nginx plugin does not appear to be installed

I made some searches on Google and here and I still can't figure out which plugin is missing or an other way to fix this.

Does someone have an idea tohelp me ?

Thanks a lot :)
