Upgrade to ACMEv2 Client

Which version of the certbot client does support ACMEv2 by default? I could not find any informations about that.

I just upgraded from 0.21 to 0.28. Is this enough?

The latest version of certbot is 1.1.0.
You should always attempt to upgrade to the latest version to avoid issues with different integration/implementation changes.

What’s your OS?

P.S. certbot should change your api to v2 by default on client v0.26.0 (or a minor version later). 0.28.0 should upgrade you automatically. (If you are still on apiv1 after the upgrade, please manually update your endpoint to use v2.)

Thank you


Thank you. I’m currently using Debian 9.4. Certbot 0.28 seems to be the latest version on the mirror for that OS.

According to the man page, certbot is now using “https://acme-v02.api.letsencrypt.org/directory” as default server, which looks fine to me.

I have an other server running certbot 0.26.1. But the client still uses v1. The automatic update does not seem to happen. How can I manually update the default server to v2? Updating certbot is a bit more complicated on this server because it is provided by a plugin which does not currently have an update.


You should use --server https://acme-v02.api.letsencrypt.org/directory to force certbot use ACME v02 API.
Example: sudo certbot renew --server https://acme-v02.api.letsencrypt.org/directory

Thank you
