Sadly, you did not return the favor by answering my question.  I'll repeat
it since you snipped it:

    b) Run gpsdebuginfo as root, and send us that output.  Your gpsd is too old,
    so get a copy here: https://gpsd.io/gpsdebuginfo

I can't say without the gpsdebuginfo.  It could be that the flight
controller is reprogramming the GPS to not use the USB.

As for sudo:

Otherwise, I never use apt, someone else will have to answer that.

My suggestion is that you do whatever your normal system update routine
is.  If that does not work, install gpsd from tar ball or git.

As I said, I despise systemd(ilbert).  I have no idea how to configure it.

Maybe someone else can help with that.
