Apache error Digital Ocean Ubuntu 18

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:174.138.51.31

I ran this command: sudo certbot --apache

It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log
The apache plugin is not working; there may be problems with your exiting configuration.
The error was: NoInstallationError('Cannot find Apache executable apahe2ctl')

My web server is (include version): ???

The operating system my web server runs on is (include version): Ubuntu 18.04 (LTS) x64

My hosting provider, if applicable, is: Digital Ocean

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):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): Certbot 1.18.0

I am very new to Ubuntu and would like to learn it from the mistakes and errors that I encounter. Any and all help is appreciated.

Hi @edrivas411, welcome to the LE community forum :slight_smile:

How was Apache installed?
Have you tried using the --webroot method?

I am new and just follow the commands Ubuntu tells me when I do something wrong or what a website tells me. I do not recall ever installing apache.

Do you have a website there?
If so, which web server are you using for that?

I have a unifi controller on there. Today I got my message to renew my cert.

Please show the message.
And the output of:
certbot certificates

And when did you install certbot?

Your certificate (or certificates) for the names listed below will expire in 10 days (on 09 Sep 21 02:28 +0000). Please make sure to renew your certificate before then, or visitors to your web site will encounter errors.

output of certbot certificates

no certificates found.

I am just realizing that it was for a previous controller I used under same website.

I am so glad you responded or I would have been searching to fix this for days

The more information you hold back the less we can help you (with).

I was not holding back I just removed the greeting and closing.

Hello,

Your certificate (or certificates) for the names listed below will expire in 10 days (on 09 Sep 21 02:28 +0000). Please make sure to renew your certificate before then, or visitors to your web site will encounter errors.

We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See Integration Guide - Let's Encrypt for details.

For any questions or support, please visit: https://community.letsencrypt.org/ Unfortunately, we can't provide support by email.

For details about when we send these emails, please visit: Expiration Emails - Let's Encrypt In particular, note that this reminder email is still sent if you've obtained a slightly different certificate by adding or removing names. If you've replaced this certificate with a newer one that covers more or fewer names than the list above, you may be able to ignore this message.

If you are receiving this email in error, unsubscribe at:

Please note that this would also unsubscribe you from other Let's Encrypt service notices, including expiration reminders for any other certificates.

This is generally not considered a domain:

This, however, is always considered a domain:

And we can start helping you now, with that information.

Oh I am sorry I thought the domain was the main site and not the site within the site as I see it. I am really new to this so I am sorry I was not as clear as I should have been.

The name seems to have been renewing for many months now without issue.
Has anything changed in the past few months?

Yes the controller went down so bad I just had to scrap the droplet and rebuild it. The new method I used to rebuild it did not have lets encrypt on it. I now need to figure out how to add it. Previously I used crosstalk solutions 15 minute guide and this time I used a unifi guide to build it

Well therein lies the problem.

Did that guide cover TLS/SSL/HTTPS/Encryption ?

No it does not. So I need to figure out how to do it. There is an issue with Ubuntu 18 and Unifi controller so it was a completely new process and I need to figure out how that process built it and then get a cert for that controller.

This page might be helpful to you:

Which for the hard-of-reading can be summarized in this key portion:

Thank You
