Hi,

I'm using a raspberry zero 2W and am trying to do the pi side of the setup, while chmodding i'm running into the problem where the return is:

~$ sudo cp piduino/tools/arpi_bins/* /usr/local/bin    
sudo: unable to resolve host piduino: Name or service not known

How do i fix this? is this user error, Linux issue or a program issue? Thanks in advance for potentially reading this.
