Lab 4.1: The repository 'https://apt.kubernetes.io kubernetes-xenial InRelease' is not signed

wh1ga

Hello,
I just got to Lab 4.1. To work on it I have created a VM and installed fresh Ubuntu 18.04.
However, the first execution of the shell scripts has failed for me because of missing curl dependency.

If anyone else encounters this just run sudo apt install curl -y and after it finishes run the shell scripts again.

I think it would be great to add curl installation to the script itself!
