[davidwowa]

I try to start osmocom-fft or one flow in gnuradio-companion. Start with osmocom-fft following log:

And

What are the steps to reproduce this?

Running commands 'osmocom-fft' or 'gnuradio-comanion'.

Can you provide any logs? (output, errors, etc.)

No response

I don't see a HackRF issue here, your problem seems to be with your GNU Radio installation.
