Sudo certbot command not found

I’m following this tutorial for my Wordpress Lightsail instance:
https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-using-lets-encrypt-certificates-with-wordpress#install-certbot-on-your-instance-wordpress
I get to the cert request and it acts like certbot isn’t installed. Anything else I could try?
