The ACME protocol version 1 is deprecated and will stop working with Let’s Encrypt in multiple steps from 2019 to 2021. See https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430
I’ve been using acmetool on Debian since Stretch. Unfortunately version 0.0.62 in Debian’s current stable release Buster doesn’t support ACME v2 yet.
So I am looking for alternatives. I really like the minimalistic design of acmetool
and that it is idempotent. (This question is not about opinions on alternatives.)
Which clients from the official Debian Buster repo already support ACME v2?
