My web server is (include version): Apache
The operating system my web server runs on is (include version): Debian 8
My hosting provider, if applicable, is: Linode
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): Cannot run certbot-auto --version. Every certbot-auto command will go to the same error that I show you above.
I need help on how to renew my certificate or fix this. Not sure what this error means.

certbot-auto is just running "apt-get update". Certbot didn't cause those errors.
Debian Jessie is old. It transitioned to Long Term Support almost a year ago. The jessie-updates repository was recently deleted from the mirrors. The last jessie-updates packages were merged into the jessie repository, so you can stop the error by commenting out jessie-updates in /etc/apt/sources.list.
(Don't disable the security repository, though!)
You should upgrade to Stretch soon.
I dunno about that.
You should research these issues, post on a Debian website, and/or ask MySQL support.
