MLAT not working after reboot


#1

Before my Internet outage, my piaware was running just fine. Once the outage happened, I shut down my piaware raspberry pi. After my Internet connection was down for a week, I booted the piaware raspberry pi running piware 3.5.1 and while the pi does connect with FlightAware, the MLAT client has failed to start.

Do I have to reinstall piaware from scratch? The logs from /var/log/piaware.log is below.

Thanks

James

How did you install piaware?
These directories look very strange.
