install letsencrypt like this a few months ago, like this:
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa: certbot / certbot
sudo apt-get update
sudo apt-get install python-certbot-apache
and it worked perfectly for my 10 domains. Currently the domains are renewed without problems. But the new domains when doing:
sudo certbot --apache -d mydomain.com -d www.mydomain.com
I get this message:
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA
but with the other domains it worked.
What commands should I use now for new domains ?:
sudo certbot --authenticator webroot --installer apache --webroot-path /var/www/mydomain.com -d mydomain.com -d www.mydomain.com
sudo certbot --authenticator webroot --installer apache --webroot-path /var/www/mydomain.com -d mydomain.com -d www.mydomain.com
