I use certbot-auto for deploying Let's Encrypt SSL certificates, and I renew certificate with crontab -e like this:
* 01 * * 1 /home/myname/certbot-auto --quiet
It has an error message like the below:
Bootstrapping dependencies for RedHat-based OSes...
yum is /usr/bin/yum
To use Certbot, packages from the EPEL repository need to be installed.
Please enable this repository and try running Certbot again.
I can't solve this error. Please help me!
