Certbot / Let's Encrypt Wildcard Certificates - Ubuntu 17.xx
Wildcard is supported as of Certbot 0.22.2
Currently, version 0.22.2 is only available on the Ubuntu 17.xx repository. Other Linux distributions may differ of course. If you currently have Certbot installed under 17.xx you may wish to "certbot delete" and "apt purge" it first. In other words you should probably start over.
Install Certbot:
At this point, just follow the prompts.
When it prompts for you to add a DNS TXT record, you will need to do that. As far as I know, other validation/plugins do not support newest LE (yet).
sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install certbot
Certbot should now be at version 0.22.2 or greater:
$ certbot --version
certbot 0.22.2Edit this file to use new/proper version of LetsEncrypt (ACME v02):
sudo nano /etc/letsencrypt/cli.ini
Add this line at end:
server = https://acme-v02.api.letsencrypt.org/directoryUpdate this line to your domain and execute:
sudo certbot --agree-tos --manual --preferred-challenges dns certonly -d *.domain.tldAt this point, just follow the prompts.
