certbot: error: unrecognized arguments: --dns-loopia-credentials loopia-credentials.ini

Having issues getting this plugin to work. I installed certbot according to instructions on their website for Ubuntu 18 LTS. Then I installed pip3 with apt install python3-pip. Then I installed your plugin with pip3 install certbot-dns-loopia as root.

Getting the following error:

certbot certonly --authenticator dns-loopia --dns-loopia-credentials loopia-credentials.ini -d *.domain.com
usage: 
  certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...

Certbot can obtain and install HTTPS/TLS/SSL certificates.  By default,
it will attempt to use a webserver both for obtaining and installing the
certificate.

It appears that certbot does not recognize the plugin as installed:

certbot certonly --authenticator dns-loopia -d *.domain.com
Saving debug log to /var/log/letsencrypt/letsencrypt.log
The requested dns-loopia plugin does not appear to be installed

And if I try to remove all installations of certbot and only install using pip (apt install python-pip) I get this error:

pip install certbot-dns-loopia

Any help getting this to work greatly appreciated.

Installing cerbot using snap (which is the recommended method) does not work with plug-ins installed using a traditional pip method. I have started to look into how to package this plug in as a compatible snap packet but haven't had time yet.

So, at the moment you have to wait or install certbot in some other way.

Thanks, I understand. I also tried installing both plugin and certbot with pip and pip3 but had issues with both, see updates to comment. Any tip on how to get it working?

[kmpm]

Please try pip3 ( uses python3 instead of python2 which pip does ) for both. Do you get the same error then (unlikely since it should use python 3.x) Python 2 is indeed not supported any more.

I tried that but I'm getting the following error when running certbot after installing with pip3 which I'm guessing has nothing to do with this plugin:

certbot --version

Just wanted to let you know that I tried the snap-wrapped plugin instead and that worked without any issues.
