Letsencrypt certificate issue

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:example.com

I ran this command:certbot certonly --nginx -d example.com

It produced this output:certbot not found

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Two things:

1: have you installed Certbot before you ran the command?

2: please also answer the rest of the questionnaire. Your real domain is mandatory.


I'm getting ready for the next problem...
nginx is not found.
