How to install certbot-dns-ovh?

On the documentation page there are no installation instructions.

I installed this plugin before on ubuntu 16.04 about a year ago. That time i was using the command python3 -m pip install certbot-dns-ovh. Which i’m sure i grabbed from a documentation somewhere (i can’t find this documentation anymore). However this command no longer works because i get the following issue

Does anyone know how to install this plugin?

I prefer not use docker if that’s possible.

The certbot-dns-ovh plugin was never packaged by the Ubuntu PPA maintainers - though some others were.

It’s probably easier to use something like if you need DNS plugins, at least until the packaging situation has improved.

If you use certbot-auto rather than the apt package, it’s “kind of” possible to muddle through and get the DNS plugins. It basically involves modifying your cronjob to ensure that the OVH plugin is always installed, with:

/opt/ install certbot-dns-ovh

For example, if the regular cron job was:

0 0,12 * * * root python -c 'import random; import time; time.sleep(random.random() * 3600)' && /usr/local/bin/certbot-auto renew

You might change it to:

0 0,12 * * * root python -c 'import random; import time; time.sleep(random.random() * 3600)' && (/opt/ install certbot-dns-ovh; /usr/local/bin/certbot-auto renew)

Not exactly elegant or supported but it avoids problems with incompatible packages.

Hi _az thanks for your answer. I commented the line i had

0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(43200))' && certbot -q renew

And put a new line

0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(43200))' && (/opt/ install certbot-dns-ovh && certbot -q renew)

How can i initialize cerbot with the parameters i was passing before? I like to do an unattended installation. Before i was doing:

certbot -m $LETSENCRYPT_EMAIL --dns-ovh-propagation-seconds 60 --dns-ovh-credentials $CREDENTIALS_PATH --redirect --agree-tos -a dns-ovh -i nginx -d "*.$HOSTNAME" -d $HOSTNAME --server

Should i run this same code once to set everything up?

By the way, i noticed that certbot-auto help menu is changing when you call it a second time. I’m not sure why that is.

First time

It’s because

The first time you run certbot-auto, it downloads and installs a copy of certbot. Prior to that, the Certbot software itself isn’t present on your system.

schoen, is it so that certbot-auto replaces certbot? And should i pass flags to certbot-auto instead?
