Unable to run install -n

So in the first line of /etc/asterisk/asterisk.conf I had removed the ! in the first line directories because of another article I had found (linked below). I’ve put the ! back into the file and now I’m just getting the same error as described in the link below.

Reading /etc/asterisk/asterisk.conf…Error!
Unable to read /etc/asterisk/asterisk.conf or it was missing a directories section
