This screenshot either does not contain copyright-eligible parts or visuals of copyrighted software, or the author has released it under a free license (which should be indicated beneath this notice), and as such follows the licensing guidelines for screenshots of Wikimedia Commons. That isnt likely to work on Ubuntu 15.10 at the moment as it currently relies on very new versions of some libraries.The package you would need to install to support it is 'libcapnp-dev' rather than 'capnproto', but the version in 15.10 is too old for the current 3.0-integration code.
