Updating to ACMEv2 Compatible Client

Help
1

I received an email from noreply@letsencrypt.org with subject Update your client software to continue using Let's Encrypt. It stated:

On June 1, 2021, you will no longer be able to renew your certificates using
ACMEv1. You should upgrade to an ACMEv2 compatible client before then, or
certificate issuance will fail. For most people, simply upgrading to the
latest version of your existing client will suffice. You can view the client
list at: ACME Client Implementations - Let's Encrypt - Free SSL/TLS Certificates

According to our records, your Let's Encrypt software client renewed a
TLS/SSL certificate recently using the ACMEv1 protocol. Here are the details
of one recent ACMEv1 request from each of your account(s):

User agent: CertbotACMEClient/0.23.0 (certbot; CentOS Linux 7 (Core)) Authenticator/webroot Installer/apache (renew; flags: n) Py/2.7.5

i am not very experienced, can someone tell me the command lines that i need to launch via ssh so i can update to what is required?

Thanks in advance

Hi @Soluzioni

your Certbot is too old.

Please start there:

Thank you for the quick reply, but that's where the problem lies, I really don't know where to start.

These are the specific instructions for your system here, for which you can copy paste the commands: Certbot - Centosrhel7 Apache

You might also be able to just upgrade your client, if you installed it from EPEL (but I'm not sure if you did):

sudo yum upgrade python2-certbot-apache
