Comment 46 for bug 1442105

/usr/bin/test_gps is known to segfault and we should totally remove it.

For "Why not gpsd?": It does not support assisted GPS in the way we need it, nor does it provide any sort of fusioning of network- and satellite-based positioning ootb. More to this, the NMEA that is reported back here does not report a position either, all the respective entries are marked invalid.

Let's focus on the issue at hand.

The bug is marked as incomplete as:

(1.) we fail to reproduce it reliably
(2.) spot something meaningful in the logs that tells us what is going wrong

With that, it would be very helpful if you could provide us with the information described in the forensics doc: https://wiki.ubuntu.com/Process/Merges/TestPlan/location-service#Forensics

If you are fine with switching your image to rw, the output of:

  > sudo apt install ubuntu-location-service-examples
  > sudo GLOG_v=1000 GLOG_logtostderr=1 /usr/lib/*/ubuntu-location-service/examples/client --bus system

would be very helpful.
