Error using APM: [RC_Input_Navio2]: failed to open channels


I see that somebody has already asked about this problem,

but it’s not clear to me how it was resolved. This is a new installation with the recommended RPI image and, i believe the latest APM softwatre, yet I’m still getting this error immediately on trying to start ArduCopter.

Is it not possible to start the software without an RC transmitter/receiver? I currently just want to test the navigation instruments on the Navio2, so don’t actually want to install it on a vehicle yet. Does anyone have any ideas?


Have you tried to reboot after sudo apt-get dist-upgrade? It seems you haven’t!

I will run through the process again, and make sure I do this time.
