Hello everyone, We are definitely planning on trying to get letsencrypt into jessie-backports. At the moment, we're waiting on the upload of a couple of its dependencies into backports; I've been talking to the maintainers of those packages to try and move that process along.
It will, unfortunately, FTBFS with some of the dependencies that are currently in jessie and jessie-backports. Sincerely, -- Harlan Lieberman-Berg ~hlieberman
