Hello! I'm new to Linux and RPI too, that's why wanna apologize for stupid questions.
Have the same problem installing audio players (Moode Audio, Volumio, Max2Play...) - the installation complites with this:

No web interface access (obviously no new ip adresses appear in LAN).
I don't think it is hardware problem, because OpenElec runs fine on my RPI.
Hardware - PRI Model B, HiFiBerry Digi+
I'd be very glad to hear sujestions!
