Failed to start ArduPilot for Linux !?

I’m using the default Arducopter/Pilot image provided for the Navio2 hat/Arducopter 4.0.0. And besides several serial and i2c communications issues, now getting this message.
Any help would be appreciated.

Hi @gusevargas,

Please run the following command and post the output in the thread:

sudo journalctl -u ardupilot

Please disregard previous. I figured it out. The 40 pin header connector came loose between the pi and the navio board…
