But you can see there is an info:
*[INFO] [GPS] Found an internal GPSDO: LC_XO, Firmware Rev 0.929b*
Also, when I run /usr/local/lib/uhd/examples/sync_to_gps
It shows:

**************************************Helpful Notes on Clock/PPS
Selection**************************************
As you can see, the default 10 MHz Reference and 1 PPS signals are now from
the GPSDO.
If you would like to use the internal reference(TCXO) in other
applications, you must configure that explicitly.
You can no longer select the external SMAs for 10 MHz or 1 PPS signaling.
****************************************************************************************************************
Waiting for reference lock...LOCKED
Error: ValueError: locked(): unable to determine GPS lock statusThis could
mean that you have not installed the GPSDO correctly.
