I’ve got two machines. One I can use certbot challenge cloudflare dns with no problems.
The other I cannot. This one if I type certbot it finds no binary. But the certificate command that I currently use is certbot-auto with manual dns update.
I’d like to use cliudflare for this also, but typing certbot-auto plugins shows no cloudflare, and if I install with pip it still does not show up.
Both systems seem to be git based. I assume there are Debian/Ubuntu packages? It’s hard to tell when looking through the documentation as to what is the old/new ways of doing things.
certbot-auto is generally fine, but it doesn’t yet support a convenient way to install the DNS plugins; you’re probably best off installing Certbot from the packages if possible.
