I was unable to automatically install the SSL certificate Let's Encrypt on Centos 6.9.
The site works in this configuration: Apache + Nginx.
I install for Apache.
Instruction here: https://certbot.eff.org/#centos6-apache
It produces such errors:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Could not install OS dependencies. Aborting bootstrap!
Sorry for my google English
