A different certbot error on Debian 8

[sahsanu]

Hello @HippoMan,

@HippoMan

(1) Somehow capture the UID that certbot is requiring to go into an "_acme-challenge" TXT record.
(2) Set up the "_acme-challege" TXT record for the domain with this UID.

I manage my own DNS via "djbdns" (specifically, with "tinydns"), and so I can easily perform step 2. But I'm not sure about step 1.

certbot will pass to your script the variables CERTBOT_DOMAIN containing the domain being authenticated and CERTBOT_VALIDATION containing validation string that you must use on the txt record to validate your domain.

Here is the doc with several examples User Guide — Certbot 2.7.0.dev0 documentation

Cheers,
