Arduino Yun and webstreaming

Hi guys,
I have a problem… I connect a webcam to my yun, I followed this guide “http://www.lucadentella.it/2013/11/15/yun-colleghiamo-una-webcam-1/” + “http://www.lucadentella.it/2013/11/18/yun-colleghiamo-una-webcam-2/2/”, but when I write arduino.localhost: 8080 in the browser is configured everything fine but do not I see streaming. Sorry for the english but I’m Italian.

In these cases, when you follow someone's article or tutorial, you should ask support to its author

However, have you already upgraded the yun? mjpg-streamer is available in the package list and you don't need to download it from unknown websites

Can you detail the steps you have taken?
