To get a wildcard SSL certificate from LetsEncrypt you need to run certbot version 0.22 or later according to https://community.letsencrypt.org/t/acme-v2-production-environment-wildcards/55578

I've installed certbot from apt using

sudo apt-get install certbot

However, that reports:

certbot is already the newest version (0.17.0-2).

How can I upgrade certbot to a version that supports wildcard certificates?

If you have already installed Certbot, you should add a parameter to apt-get install to upgrade only a specific package

sudo apt-get update
sudo apt-get install --only-upgrade certbot

Check version number

certbot --version || /path/to/certbot-auto --version

  • When I asked this question, the problem was that apt didn't have the latest version of certbot available. I'm glad to see that it now has a new enough version to do the DNS verification for wildcard certs. – Stephen Ostermiller Feb 12 '19 at 22:26

As the certbot site indicates, the certbot team maintains a PPA. The certbot package is at 0.22.2 on all supported versions of Ubuntu in that PPA. (What are PPAs and how do I use them?)

Check version number:

certbot --version

On Ubuntu systems, the Certbot team maintains a PPA. You can add it to your list of repositories and install Certbot by running the following commands:

$ sudo apt update
$ sudo apt install software-properties-common
$ sudo add-apt-repository universe
$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt install certbot
