Underlying reason seems to be that I used a different username than ubuntu when I customized my image (when I selected a wifi connection option).
The test harness seems to assume this user (and and as a result this group) exists. Further issues like #342 also result if you use a different user from ubuntu.
@andy31415 Thank you for your feedback.
The user name must be UBUNTU for the system to work correctly.
With this in mind, we will make the installation instructions clearer so that they are not changed.
@andy31415 Please take a look and if everything is ok, could you close the issue?
