I received the email that tells me to update my certbot because of the ACMEv1 protocol.
But, which version i need? And how can i upgrade it in debian 9? Because i already updated to the lates available version (0.28) but i’m still receiving this email.
Before the email i had a version like 0.19, now i’m on 0.28.0 and is the latest version available on debian 9, there are no instructions for upgrading in the official lets encrypt website.
Thank you in advance.
