piaware MLAT python error with Airspy

FlightAware ADS-B Flight Tracking

So I have an Airspy Mini, and I am running on an ODROID with Ubuntu 16.04

airspy is feeding dump1090 but MLAT isnt running, when I look at the log I see this

5/12/2016 19:18:23 mlat(1961): Traceback (most recent call last):

so when I put the airspy on my rPI setup, the MLAT client runs fine, seems its a python environment issue?

I get the same issue. I haven’t managed to fix it yet.

so here is what I ended up having to do.

I went with the Armbian disto for the ODROID. The issue I think its the Ubuntu 16.04 from ODROID is for aarch64 and we need stuff compiled against armhf
