Using the new ekosdebugger facility, I have captured the result of running indi-gpsd. The USB gps works fine under gpsmon, but won't load with the latest build on Ubuntu 20.04 with an Odroid-N2.
First good use of the EkosDebugger! You have an older INDI installation in /usr/local, so go there and purge all INDI stuff in /usr/local/bin, /usr/local/lib, /usr/local/share ...etc
