Unfortunately, it will probably be at least a couple weeks. The PPA is maintained by Debian maintainers who just take the packages from Debian, but they haven’t had a chance to package Certbot 0.22.0 or any of its DNS plugins. The DNS plugins are needed to automate obtaining wildcard certificates because Let’s Encrypt only supports domain validation via DNS for wildcard certificates. On that note, if you have some experience with Debian packaging and would like to contribute to Certbot by helping our Debian maintainers with this, please get in touch.
We’ll be doing what we can on our end to move things along. In the meantime, keep an eye on https://certbot.eff.org for instructions on how to workaround these limitations while we wait for packaging to catch up.
