I'm using a live usb version of Ubuntu while attempting to the instructions outlined in the documentation of Windows 10 AME and am stuck here. The full command is:
sudo chown <your user>:<your user> /media/ntfs
I've tried inputting what's shown at the top of the terminal window ubuntu@ubuntu:~ but I get 'invalid user' in response.
