Package: letsencrypt
Version: 0.1.1-3
Severity: normal
Tags: ipv6 upstream

Dear maintainer,

while trying to obtain a letsencrypt certificate on an IPv6-only the
only result is:
Failed authorization procedure. ipv6only.my.domain (http-01): urn:acme:error:unknownHost :: The server could not resolve a domain name :: No IPv4 addresses found for ipv6only.my.domain

 - The following 'urn:acme:error:unknownHost' errors were reported by
   the server:

   Domains: ipv6only.my.domain
   Error: The server could not resolve a domain name

Since experimenting with new concepts like letsencrypt will be happening
more likely on IPv6-enabled (and potentially IPv6-only) hosts, it'd be
nice if there would be a workaround/fix to get this flying.



P.S.: yes, the hostname was edited and I have tried with a public FQDN
      that's IPv6-only
