Letsencrypt how to use --preferred-challenges
This command:
$ letsencrypt certonly --manual --preferred-challenges dns --email [email protected] --domains test001.bar.com
outputs:
letsencrypt: error: unrecognized arguments: --preferred-challenges dns
From the documentation here: https://certbot.eff.org/docs/using.html#certbot-command-line-options
I find:
--preferred-challenges PREF_CHALLS
A sorted, comma delimited list of the preferred
challenge to use during authorization with the most
preferred challenge listed first (Eg, "dns" or "tls-
sni-01,http,dns"). Not all plugins support all
challenges. See
https://certbot.eff.org/docs/using.html#plugins for
details. ACME Challenges are versioned, but if you
pick "http" rather than "http-01", Certbot will select
the latest version automatically. (default: [])
Why do I get this error?
Answer
Found the answer, although the website states that letsencrypt and certbot are the same. It seems to not be the case.
$ apt-get install letsencrypt
$ apt-get install python-pip
$ pip install --upgrade pip
$ pip install certbot
$ certbot certonly --manual --preferred-challenges dns --email [email protected] --domains test001.bar.com
Does the trick
