Thanks, but building from sources usually introduces fewer surprises. For example, when using the instructions you gave, I get.

Is it possible to get the libknot package on Ubuntu 16.04.4 LTS updated soon? If not, how do I install the latest libknot by hand?

The easiest way to get *newest* released knot-resolver for a few distributions should be via:
https://software.opensuse.org//download.html?project=home%3ACZ-NIC%3Aknot-resolver-latest&package=knot-resolver

This new distribution approach hasn't fully settled yet, but it should work already.
