The buffered stderr had me scratching my head for quite a while. What a crazy decision on the part of the python developers!!

I didn't even know about the buffer since I hadn't had a chance to use stderr (was mostly doing django). I did some research and I can see how that is a problem in OP25 haha.
Looks like there might be another error with the HTTP interface.
The first error is
osmosdr source_c creation failure with the full error being:
Python:
gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.8.1.0
built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy airspyhf soapy redpitaya freesrp

gain_names = self.src.get_gain_names()

That error normally happens when gr-osmosdr cannot find the sdr hardware. Does the rtl device show up when you run "lsusb" command?

Woops, you're right. I forgot to attach it to my VM. All good now!

Actually, I'm getting this error now:

Fixes posted and available in origin/master (as well as origin/dev). I've tested the gui commands and fixed a couple non-python3 bugs I ran across along the way.
If anyone has a suitable testing environment with the ability to make an apples-apples comparison, I would be curious to compare CPU utilization of op25 under gr3.8/py3 versus the same hardware & configuration running on gr3.7/py2.
As an aside, my test environment is happily running an Airspy @ 3.0Mhz with glitch-free audio via the much-maligned 'pulse' subsystem on Ubuntu 20.04 in a virtual environment using Virtualbox on host Mint 18.3 (Ubuntu 16.04).

I have VMWare workstation, so I can create two VMs to do testing on the same CPU(s). I'll do Ubuntu 18.04 and Ubuntu 20.04 for testing.
