New error this week: certbot-dns-digitalocean says: (acme 0.31.0 (/usr/lib/python3/dist-packages), Requirement.parse('acme>=0.40.0'))

Ubuntu 18.04.03, just spun up…

Using apt repos and packages:

  • ppa:certbot/certbot
  • python-certbot-apache python-pip python3-pip
  • pip install certbot-dns-digitalocean
  • pip3 install certbot-dns-digitalocean
  • Tried pip and pip3 each/both every way

Then, each of these…

certbot certonly --dns-digitalocean --dns-digitalocean-credentials /path/to/digitalocean/apikey...
certbot --apache certonly...
certbot --manual certonly --preferred-challenges=dns...

Returns the error:

pkg_resources.VersionConflict: (acme 0.31.0 (/usr/lib/python3/dist-packages), Requirement.parse('acme>=0.40.0'))

Is the certbot-dns-digitalocean pip package just out of date? I can’t find anyone else asking.

It seems to work for me after installing an earlier version of the pip package managing the dns-challenge.

You are not alone, I faced the same error today (not on digital ocean) on a clean server.
