[Discuss-gnuradio] PyBOMBS install GRC and UND errors on Ubuntu 18.04

[John_w_g]

I have installed GRC and UHD via PyBOMBS on Ubuntu 18.04.  I am working with a Ettus x310.  I cab successfully run uhd_usrp_probe launch GRC that finds the SDR correctly.  I wrote a simple GRC program that creates a tone, sends it to the transmitter ad then through a loopback to the receiver for display in the Qt display as an initial functional test.  When I launch GRC via

PyBOMBs run gnuradio-companion

I get the attached warnings and errors output in the console.

The system displays on the frequency plot only a small -100 dBm tone at 0-Hz no matter

what RX and Tx gain settings I use.  I assume this is LO leakage.  GRC continually outputs 'Gt" error codes in the console. When I attempt to end GRC it will hang and I have to force it to close.  I have attached the console output when I launch GRC

Any input on what I need to modify/change to get this working properly would be greatly appreciated.
