Problem to install certbot auto nginx: nginx plugin is not working

Help
1

My domain is:trj.it

I ran this command:
sudo wget https://dl.eff.org/certbot-auto
sudo mv certbot-auto /jet/etc/letsencrypt/certbot-auto
sudo chown root /jet/etc/letsencrypt/certbot-auto
sudo chmod 0755 /jet/etc/letsencrypt/certbot-auto
sudo chmod a+x /jet/etc/letsencrypt/certbot-auto
sudo /jet/etc/letsencrypt/certbot-auto --nginx

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
The nginx plugin is not working; there may be problems with your existing configuration.
The error was: NoInstallationError(“Could not find a usable ‘nginx’ binary. Ensure nginx exists, the binary is executable, and your PATH is set correctly.”,)

My web server is (include version):

The operating system my web server runs on is (include version):
Linux lemp7-optimized-g2-1-vm 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 (2018-08-21) x86_64

My hosting provider, if applicable, is: google cloud compute engine

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

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

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

A note: I have changed 10 hours ago the nameserver … it may be that I have to wait for the propagation before installing

Hi @RickyIta68

Certbot can't find your nginx.

Do you use non-standard directories?

Check

https://certbot.eff.org/docs/using.html

there are two additional options:

  --nginx-server-root NGINX_SERVER_ROOT
                        Nginx server root directory. (default: /etc/nginx or
                        /usr/local/etc/nginx)
  --nginx-ctl NGINX_CTL
                        Path to the 'nginx' binary, used for 'configtest' and
                        retrieving nginx version number. (default: nginx)

Hi Juergen and thank you for reply and happy Easter

I also, before, tried to install certbot auto in other directories (/etc/letsencrypt/certbot auto )
but returned the same error …

ok, now I will try in this way :

sudo wget https://dl.eff.org/certbot-auto
sudo mv certbot-auto /jet/etc/letsencrypt/certbot-auto
sudo chown root /jet/etc/letsencrypt/certbot-auto
sudo chmod 0755 /jet/etc/letsencrypt/certbot-auto
sudo chmod a+x /jet/etc/letsencrypt/certbot-auto
sudo /jet/etc/letsencrypt/certbot-auto --nginx --nginx-ctl /usr/sbin/nginx --nginx-server-root /etc/nginx

At the time I uninstalled certbot auto:

sudo unlink /jet/etc/letsencrypt/certbot-auto
sudo rm -r /opt/eff.org

I can’t get it to work unfortunately. It’s strange because in another vm instance identical to this one I performed the same procedure and I didn’t have any problems.

I don’t know how to solve

here there is a doc about the jetware vm istance:

OK I have solved the problem … and I hope to have not problem with the renew of the certs

I have added a line to nginx.conf
user nobody nogroup; before launching the command:
sudo /jet/etc/letsencrypt/certbot-auto --nginx --nginx-ctl /jet/bin/nginx --nginx-server-root /jet/etc/nginx
