The requested apache plugin does not appear to be installed

I ran this command:

sudo certbot --apache

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
The requested apache plugin does not appear to be installed

This is the output of the logs:

My web server is (include version): Apache/2.4.7 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu 14.04

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.35.1

Any ideas? I’ve tried everything I could find on any forums.

Hi @igorop,

Welcome to the community forum! Please review the certbot installation instructions at https://certbot.eff.org/lets-encrypt/ubuntutrusty-apache.

Let me know if this fixes the issue.

sudo apt-get update
sudo apt-get install python-certbot-apache 

I’ve tried it. No change.

What does “sudo which certbot” show? How was Certbot installed? Is the Apache plugin installed?

What did the apt-get install command do?

@igorop

Following along with @mnordhoff, I was able to successfully install certbot and the apache plugin in an Ubuntu Trusty (14.04) container.

Can you show us the output of which certbot and sudo which certbot please?

/usr/local/bin/certbot

Exact same issue here

Here’s what I noticed on an Ubuntu 19.04 machine that has been upgraded through several Ubuntu releases. At one point in time certbot had been installed in /usr/local/bin/certbot.

$ which certbot
/usr/local/bin/certbot

$ sudo apt install python-certbot-apache -y

I then sudo rm -f /usr/local/bin/certbot, restarted my shell, and ran the following. This showed me exactly what I expected. Can both of you try that?

$ which certbot
/usr/bin/certbot
