Not clear to me how to update from ACMEv1 to ACMEv2

I am running on an AWS Linux AMI running Apache/2.2.34
“yum” is the tool used to grab software from repositories.

Have received several e-mails regarding upgrading to ACMEv2, however my certs look fine and test fine.

my “crontab -l” shows certbot running properly
0 1,13 * * * /home/ec2-user/certbot-auto renew

and I see no errors when I run against Qulays’ SSLlabs.

Do not see any need to upgrade but I am still getting e-mails from you. If I do need to upgrade the instructions are not very clear. Any help would be appreciated.

Hi @intheclouds

Ssllabs isn’t relevant, if you have created certificates.

Check your certbot config files if there is an string used.

If yes, update to


Please show the output of:
/home/ec2-user/certbot-auto --version

It looks like you may have multiple versions of python installed or outdated packages…

A post was split to a new topic: ACMEv1 notice after upgrading Certbot

Any idea how to resolve this? I have not touched this certbot app in almost two years. The version of python that the certbot app is using appears old (2.7.x) yet the machine was built in July 2018 and has been constantly updated since.
