i received the ’ Action required: Let’s Encrypt certificate renewals’ email saying that ‘Your Let’s Encrypt client used ACME TLS-SNI-01 domain validation to issue
a certificate in the past 60 days.’
I am trying to upgrade from an old certbot 0.10.2 to the latest version, but nothing I have tried works without giving errors.
I’m on Debian Jessie running Apache.
I have run
apt-get upgrade and
apt-get update, but cretbot has not been updated from 0.10.2
I’ve looked at
https://community.letsencrypt.org/t/how-to-stop-using-tls-sni-01-with-certbot/83210 but I have an error running: certbot renew --dry-run which gives me
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA. which, from reading, means that I need to update certbot, but I’ve not been able to.
Is my only option to remove certbot and install certbot-auto as mentioned here: https://certbot.eff.org/lets-encrypt/debianjessie-apache ?
Not sure how to proceed.
