I just upgraded my server from ubuntu 14.04 using webroot on nginx I think with certbot-auto for renewals to 16.04.1 lts.
It appears to still be working, but I’d like to upgrade to the ubuntu 16.04.1 letsencrypt package. Do I just follow the install instructions for letsencrypt from the beginning? I do need to add some additional domains, so a full reinstall wouldn’t hurt, but is there anything I should keep in mind by following the instructions found here: https://certbot.eff.org/#ubuntuxenial-nginx
I currently have a cert for my primary domain…but I’d like to add certs for all of my domains…do I specify them all in one go or do I do them individually? Do I have to do one with www and one without if I want my site to be secure with and without www?
Thanks for the help!
