Ok, fixed.
Solution from #5 is no longer valid, see
KSP-CKAN/CKAN#1787

Mono users on Linux no longer need to run mozroots to get SSL working. A new command, cert-sync, has been added to this release, which synchronizes the Mono SSL certificate store against your OS certificate store – and this tool has been integrated into the packaging system for all mono-project.com packages, so it is automatically used when you install Mono via our packages. Just make sure the ca-certificates-mono package is installed on Debian/Ubuntu (it’s always bundled on RPM-based distros) to take advantage! It should be installed on fresh installs by default.

Theca-certificates-mono package not is on the repositories of Debian 8 stable. So you must use the mono repositories directly

Not works for me, I'm doing something wrong?

$ mozroots --import --ask-remove
Mozilla Roots Importer - version 3.2.8.0
