[yocto] do_fetch error

[mohammed aqdam]

Hello there,

I was build image for rpi3 using yocto, but the image which i build
was not supporting camera(picamera),so after googling for a while i found
this link

https://github.com/pauldotknopf/raspberry-pi-camera-source

now while building, i'm getting the following message...
