XBIAN + RetroPie

[Tozzi]

Hi,

I'm new to this forum, using the current version of XBIAN (20161221-0) on a brand new Raspberry PI 3.

So far, everything works like a charm, but unfortunately I am not able to install RetroPie.
RetroArch and emulationstation refuse to install because of missing libraspberrypi-dev.

When I try to install this package I get:

Code:

Package libraspberrypi-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  xbian-package-firmware xbian-update

E: Package 'libraspberrypi-dev' has no installation candidate

Sorry if this is a stupid question but I've been googling for many hours without getting any clue how to fix this.

Any hint will be highly appreciated. I've spent many hours on configuring XBIAN and would hate to have to switch to another distribution.
