Using Krypton : I cannot install My Pictures Database

Hello,

I try to install My Pictures Database addon.
I do follow the guide, and at the end, when I click the “Install” button”, nothing is downloaded : back to previous extension page.
No error message, it’s like the super repo repository simply does not work (tried other addons on same page without success too)

A simple question : is super repo repository “Krypton-compatible” ?

Thanks.
