I followed a guide for installing Plex Media Server on Raspbian on YouTube. In the guide it was successful but when I tried to execute in on my own RPI 3 it didn't work. See the terminal output below:

Downloading readynas package ...

For those who encountered this, just re-run it until its successful, seem to be from what i experienced, its something about the peer being refused or something. Just look up errno 104 on google. Yes, don't give up just re-run it. nothings wrong with your pis
