I upgraded from Ubuntu 14.04 to 16.04 a few months back. Now my certs have expired. After looking to see why my auto renew didn’t work, I find no trace of certbot. All my /etc/letsencrypt files are still there including the /etc/letsencrypt/renewal files.
What is the best way forward from here? Can I just re-install certbot without messing anything up?
My web server is (include version): Apache 2.4.18
The operating system my web server runs on is (include version): Ubuntu 16.04.6
I can login to a root shell on my machine (yes or no, or I don’t know): Yes
