ERROR: Cannot request a certificate without an e-mail address!

[leandroramos]

Hello, I tried to deploy as follows:

wget "https://shokku.dev/bootstrap.sh"
export SHOKKU_LETSENCRYPT_EMAIL="foo@example.com"
bash bootstrap.sh

But I got the error:

==> enabling letsencrypt
=====> Enabling letsencrypt for shokku
 !     ERROR: Cannot request a certificate without an e-mail address!
 !       please provide your e-mail address using
 !       dokku letsencrypt:set shokku email <e-mail>

You need a valid email address for letsencrypt to get encrypted http connections. Otherwise probably everything works but only with http (not https). Still, you probably want https because browsers and search engines do not like unsecure connections.

I have a valid e-mail. I've tried 3 different valid e-mails. This is the complete log:
