I’m a bit confused as to the naming of certbot. If I understand the history, the letsencrypt-auto client was recommended a long time ago (when letsencrypt was in beta). Then the certbot project came out and that became the recommended client.
For the Ubuntu 14.04 LTS Certbot install instructions, the recommendation is to download certbot-auto and install manually.
For the Ubuntu 16.04 TLS Certbot install instructions, the recommendation is to install the “letsencrypt” package through apt. (This package seems to behave just like certbot, but it provides a command letsencrypt-auto just like the old client). Is this the certbot client or the older letsencrypt client?
For the Ubuntu 16.10 Certbot install instructions, the recommendation is to install the “certbot” package through apt.
Is the go-forward Ubuntu recommendation to use the certbot apt installer? Just wondering what client I should expect to be coding into my provisioning scripts since the name and the install instructions have changed over time.
