How to upgrade Let's Encrypt certificate from ACMEv1 to ACMEv2?

Question

Nginx

I can not solve the problem with updating certificates from ACMEv1 to ACMEv2 due to the fact that ACMEv1 is outdated and no longer supported.

The server is running Debian 8.

certbot -- version
0.10.2 and writes that the version has been updated to the latest.

I updated it manually with the following command:

sudo certbot certonly -a webroot --webroot-path=/var/www/example.com/www/ -d example.com -d www.example.com

At the moment I tried different options and not one yet did not bring positive results.

Answer 1

Your Debian is too old, so there are no new versions. You can, of course, try to download the actual binary (or try to compile from source) - but not the fact that it will work. I would still update the OS.

Answer 2

Download the latest version of certbot-auto from the official repository
https://github.com/certbot/certbot/releases/tag/v1.14.0
and use it.
