error: invalid serial port

So I am posting this to help someone else who might run into this problem.

When following the guide I would get to the point I wanted to run the proxmark.
Dmesg|grep -i usb

confirm its ttyACM0
Then

cd client
  ./proxmark3 /dev/ttyACM0
and I get        ERROR: invalid serial port

Try adding a ***SUDO***

sudo ./proxmark3 /dev/ttyACM0

what a stupid problem to have.

Thanks for the trick. I had the same problem on Ubuntu.

Re: error: invalid serial port

Or you can, you know, fix the permissions problem and give the user you're logged in as read permission to the serial port.

sudo is bad, mmmk?
