How did you do THIS step:

1. Add the mymoves repository to your phone:
- Create a file called /etc/apt/sources.list.d/mymoves.list
- Into that file, enter this line (without the quotes): “deb http://koti.kapsi.fi/~sh8dfwk/mymoves binary/“

I made a file in windows notepad with that text called mymoves.list, USBtansferred it to Downloads on the N9.

When I go to the terminal and put in "mv /home/user/MyDocs/Downloads/mymoves.list /etc/apt/sources.list.d/mymoves.list" it just says "mv: can't create '/etc/apt/sources.list.d/mymoves.list': permission denied"
