Specs

# Automation of SSL and certificate renewal for Apache 2 on Ubuntu
# Totally based on the document at:
https://certbot.eff.org/lets-encrypt/ubuntufocal-apache
# Apache Site configurations without SSL must be ready on your servers
#   Refer to ApacheOnUbuntu Tutorial
 

1. Preliminary Tasks

# 1.1. Snap Daemon
# Certbot is installed as a snap, Ubuntu 20.04 installs snap daemon (snapd) 
#   by default. If in any case it is not installed, you can install snapd by 
#   the following command:
sudo apt install snapd
# 1.2. Remove Old Certbot Packages (If any)
# If you've installed certbot's apt package before, remove it:
sudo apt remove certbot
 

2. Installation and Getting SSL Certificate

# 2.1. Ensure that your snapd (snap deamon) is up to date:
sudo snap install core; sudo snap refresh core
#
# 2.2. Install Certbot
sudo snap install --classic certbot
#
# 2.3. Get SSL Certificate
sudo certbot --apache
# Asks your email, don't hesitate giving it, you will be informed if any problems
#   occurs at the renewal of certificates.
#
# 2.4. Test automatic renewal
sudo certbot renew --dry-run
#
# 2.5. All set, certificates generated and installed, all apache
#   configurations are made, jobs added to crontab to renew certs.
#   Check crontab:
systemctl list-timers
