I am an IT student and this is the first time I work on a server and I wanted to intall letsencrypt on my Apache server. My boss told me to install the package like this :
sudo apt get install letsencrypt`
So I did not clone it from git. My boss told me too that it’s not the last version but it is ok for him. I did the following commands after installing apache :
sudo apt get install letsencrypt
sudo a2enmod ssl
sudo a2ensite default-ssl.conf
sudo service apach2 restart
sudo letsencrypt --apache -d ca-tic-app2.tic.ch
and it return me this :
ConfigurationError: Requested domain ca-tic-app2.tic.ch is not a FQDN
What should I do ?
