Getting certbot

Refer to Let’s Encrypt in Debian for Wheezy or manual setup.

For Debian 8 Jessie, enable Backports repo to install certbot.

1
echo "deb http://ftp.debian.org/debian jessie-backports main" | sudo tee /etc/apt/sources.list.d/debian-backports.list
2
sudo apt update
3
sudo apt install certbot -t jessie-backports

For Debian 9 Stretch, you just have to install it.

1
sudo apt install certbot

According Perfect Guide tutorial, we have to make a directory. I don’t know if this is a necessary thing to do. I’m doing it just for the sake of completeness.

1
sudo mkdir /opt/certbot
2
sudo ln -s /usr/bin/certbot /opt/certbot/certbot-auto

Done.
