Unable to find pre-hook command

Help
1

Hi All,

I got a really strange issue, and can’t find to get to the bottom of the problem. For some reason i got the error on what ever command i execute that the pre-hook command is not find in the PATH. Could someone guide me to get to the bottom of the case how to solve this?

My domain is:
fotoautofocus.nl
I ran this command:
sudo certbot --cert-name fotoautofocus.nl --apache --preferred-challenges http
It produced this output:
Unable to find pre-hook command /root/bin/certbot-pre in the PATH.
(PATH is /usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/vincent/.local/bin:/home/vincent/bin)
My web server is (include version):
Apache httpd-2.4.6-88.el7.centos.x86_64
The operating system my web server runs on is (include version):
Centos 7
My hosting provider, if applicable, is:
BladeVPS transip
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

For extra info by using the --disable-hook-validation i got the following output:

Hook command “/root/bin/certbot-pre” returned error code 127
Error output from certbot-pre:
/bin/sh: /root/bin/certbot-pre: No such file or directory

Hi,

It seems that you’ve specified pre & post hook when you request those certificates, did you specify it by yourself?

Is there any files / directory on /root/bin/certbot-post & /root/bin/certbot-pre?

Thank you

Also:

sudo find /etc/letsencrypt/renewal-hooks
sudo grep -R certbot-post /etc/letsencrypt/renewal

There are no files on /root/bin/certbot-post

sudo find / -name certbot:
/etc/sysconfig/certbot
/usr/bin/certbot
/usr/lib/python2.7/site-packages/certbot

sudo find /etc/letsencrypt/renewal-hooks
/etc/letsencrypt/renewal-hooks
/etc/letsencrypt/renewal-hooks/pre
/etc/letsencrypt/renewal-hooks/deploy
/etc/letsencrypt/renewal-hooks/post

sudo grep -R certbot-post /etc/letsencrypt/renewal:
/etc/letsencrypt/renewal/fotoautofocus.nl.conf:post_hook = /root/bin/certbot-post
/etc/letsencrypt/renewal/mail.fotoautofocus.nl.conf:post_hook = /root/bin/certbot-post

So at some point, you (or someone) setup these post-renewal hooks to perform some task.

If you know what they did, you can re-create them. Otherwise, you can just remove these lines from these files to avoid the error.

These are definitely customizations and not part of the default operation of Certbot.

I did it myself by following a guide how to set up Letsencrypt on CentOs7 with Apache.

So i will try to delete the lines now

Also check if they’re being specified in /etc/letsencrypt/cli.ini.

Perhaps you got them from this tutorial: https://aoeex.com/phile/postfix-dovecot-and-lets-encrypt-certificates/

You can find the certbot-post file contents in there.

yeah. does the file with the script need to be from a certain name?
