The requested apache plugin does not appear to be installed

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. https://crt.sh/?q=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: holidayshop.echo-inc.org

I ran this command: # certbot certonly --apache

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
The requested apache plugin does not appear to be installed
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

My web server is (include version): ea-apache24-2.4.62-2.3.2.cpanel.x86_64

The operating system my web server runs on is (include version): AlmaLinux release 9.4 (Seafoam Ocelot)

My hosting provider, if applicable, is: bluehost

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 2.11.0

Ah yes, there apparently is a "bug" in the pip instruction generator. It actually does not instruct to install the actual Apache authenticator plugin. See also Missing dependency in certbot instructions · Issue #9998 · certbot/certbot · GitHub where this bug was reported a few days ago.

You should install the plugin by running:

sudo /opt/certbot/bin/pip install certbot-apache

(Assuming you've used the path /opt/certbot/ as instructed in the Certbot instructions, otherwise you need to modify the path in the command above.)

That's a weird error I've never seen before. Not sure how to fix it. Google suggests some things like SELinux or /tmp/ not being able to have executable files.

Alternatively you can forget about the --apache plugin and use the --webroot authenticator and install the certificate into Apache manually.

SELinux is disabled. Not sure about /tmp not being able to have executable files. I can install the certificate into Apache manually.

Is this what you're implying that I run?

certbot certonly --webroot

For example. You can add more options to the command line or let Certbot ask the questions so you can answer them. See User Guide — Certbot 2.11.0 documentation for the webroot documentation for example.

I used this:

https://eff-certbot.readthedocs.io/en/stable/using.html#webroot

I'm all good now I think. It's downloaded the certs to the machine. Now its on to the .conf file to configure.
