I have installed the letencrypt but at the moment I have been a problem and now I try to install certbot but everytime it doesn't work. Do you have a tuto to explain all the process* I am on Jessie debian 8 https://certbot.eff.org/#debianjessie-apache Step 1 : install certbot Code: sudo apt-get install python-certbot-apache -t jessie-backports Step2 : installation of certbot certificat Code: certbot --apache Some domain appear what is the good process ? 1 -Select all the domain and continue the process or clic to cancel ? When I clic all domain and Ok, Certbot include new files in Code: /etc/apache2/sites-enabled like xxxx.org.vhost-le-ssl.conf, I clic on easy I don't know if it's correct and also it create 1 certificat and apply on all domain. 2 - -Select all the domain and or clic to cancel 3 - Unselect All domains and click to continue ? 4 - Unselect All domains and click to cancel ? Step 3 : Certificat creation with ispconfig Depends on his action when you go after in ispconfig and you select ssl, letencrypt and create new certificat, It does'nt work I think the path certbot / letencrypt it not the same, How to change exactly this path and where it can found. I am litle tired. if you have a good tuto to folle the step it will be good for everybody. Thank you.
