Trying to do this:

- 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/“

If I try

mv /home/user/MyDocs/Downloads/mymoves.list /etc/apt/sources.list.d/mymoves.list

i get this:

mv: can't create '/etc/apt/sources.list.d/mymoves.list': Permission denied

How do I fix that?
