How Set-Up Automatic Update of Let's Encrypt Certificate

Hi everyone,

Today one of my website get those email from Let`s Encrypt:


Your certificate (or certificates) for the names listed below will expire in 10 days (on 18 Jul 19 17:40 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.

We recommend renewing certificates automatically when they have a third of their
total lifetime left. For Let's Encrypt's current 90-day certificates, that means
renewing 30 days before expiration. See for details.

For any questions or support, please visit Unfortunately, we can't provide support by email.

Tell please how I could update it and make all those processes automated?

sudo certbot renew --dry-run

In Step3 you will get an answer to your question (It’s just above the conclusion.)

In my case I received a similar email but for no real reason. The certificates were automatically renewed whatsoever. Probably there was just some delay in my certbot that caused letsencrypt to send the email to be safe. My system: Ubuntu 18.04.3, certbot 0.31.0-1

You can check status of your certificates on your server by:

sudo certbot certificates

Updating certbot might also help:

sudo apt update
sudo apt list --upgradable
sudo apt install certbot
