Hi,
Is this post explaining what I want?
[Raspberry pi with duckdns DDNS failing to verify]
When I try to run:
sudo certbot certonly --manual --preferred-challenges dns --manual-auth-hook /home/pi/duckdns/auth.sh --manual-cleanup-hook /home/pi/duckdns/cleanup.sh
Certbot is not found. Where can i find the certbot script?
