Hi, I am trying to build the docker-edge-client in order to do some testing with edge apps but I'm having troubles with the build.

I'm following the instructions in the README https://github.com/IoTOpen/docker-edge-client but when I try to run the docker build command i get the following output:

Do I need to install some software or are there other steps I need to take before running the build command?
