Net.hook/create failed

Hi,
I am trying to install sphinxs on my Ubuntu 18.04, but I get the following error:
[Err] [Machine.cc:1077] Failed to start anafi4k : net.hook/create failed.
I am assuming this has something to do with network/wifi, but I don’t really know what it is. I have changed the stolen interface name in anafi4k.drone, so that is not the problem.
Does anybody know what this error means?

Hello,

Can you provide us with more info? What is the content of your .drone file? What is your command line to start sphinx? What is the name of your wireless network interface? You can get it with iwconfig.
