How to upgrade ACME v1 to v2?

Question

Digital certificates

Good afternoon,

I got the same problem
The server experienced an internal error :: ACMEv1 is deprecated and you can no longer get certificates from this endpoint. Please use the ACMEv2 endpoint, you may need to update your ACME client software to do so. Visit https://community.letsencrypt.org/t/end-of-life-pl... for more information.

Offsite did not find a clear instruction for updating the client.
Who faced, how did you solve such a problem?

Answer 1

There is a Let`sEncrypt client in Golang , it is a binary without dependencies. Just download and run .

Answer 2

Determine which ACME client is being used (certbot etc.) and update it to the latest version.
Certbot is somewhere in the repositories and is updated through the distribution's package manager - somewhere a new version of the script is simply downloaded.

Answer 3

On a certain mossy OS, a new version of the client will not be installed due to dependencies. Otherwise, just look in the standard or backports repositories.
