Problem with my IP right after installation

I just booted up Yuno on a RaspberryPi B+ and I get the big ‘Y’ and some system info. But on IP: it says nothing at all. I run ifconfig and the inet addr is What might be the problem here?

There is a problem with that image. You should put ur SD card on ur PC and put a classical /etc/networks/interfaces.

You just have to edit the file /etc/networks/interfaces on the console (connect a hdmi screen to your RPi).
And change eth0 to eth1 (or the other way round) on the two lines where it appears.
From scratch, the password of root is yunohost
To edit the file:
nano /etc/networks/interfaces
