Confirm LetsEncrypt/Certbot renew script installed?

[jamdev]

Apologies if this is really trivial, but I am just wondering if it is still necessary to create a cron job with certbot renew command in it? I followed the instructions here for installing certbot: https://certbot.eff.org/lets-encrypt/ubuntubionic-apache

The doc says there is a script installed in one of the following:
/etc/crontab/
/etc/cron./
systemctl list-timers

I ran this command: systemctl list-timers

It produced this output: Thu 2020-10-01 11:04:00 UTC 17h left Wed 2020-09-30 16:17:10 UTC 1h 21min ago snap.certbot.renew.timer snap.certbot.renew.service

My web server is (include version): Apache

The operating system my web server runs on is (include version): Ubuntu 18

I can login to a root shell on my machine (yes or no, or I don't know): yes

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.8.0

Hello @jamdev!
Welcome to the community!
Check the output of:

systemctl list-units --all | grep certbot 

And if the result looks something like:
128: certbot.service loaded inactive dead Certbot
289: certbot.timer loaded active waiting Run certbot twice daily

You're good to go!

Thanks for the timely reply! I ran the command and got this:
snap-certbot-579.mount loaded active mounted Mount unit for certbot, revision 579
snap.certbot.renew.service loaded inactive dead Service for snap application certbot.renew snap.certbot.renew.timer loaded active waiting Timer renew for snap application certbot.renew

Excellent!
You should be able to rely on the timer to do what it is supposed to do.
Your certbot snap is up to date! YAY!
Good Job!
