I have installed nuitrack on Ubuntu 20.04 following this steps.
I can run Compatibility test successfully, but I can’t activate a license key, because it always throws out this message:
Officially, Nuitrack does not support Ubuntu 20.04. However, we are aware of this problem, which is connected to an updated version of OpenSSL and its dependencies. We’ll begin testing Ubuntu 20.04 in the near future and notify our customers as soon as we add support for this platform.
