First, let’s make sure our package manager is up to date.
#apt update -y && apt upgrade -y #apt install snapd #snap install core #snap refresh core
Now, we can install certbot.
#snap install --classic certbot
Prepare the certbot command, so it can be ran from the command line.
#ln -s /snap/bin/certbot /usr/bin/certbot
Finally run de certbot to start and follow the instructions on screen.
