I figured it out! Thanks to this post: https://lists.gnu.org/archive/html/discuss-gnuradio/2017-01/msg00329.html
I apparently had multiple installations of gnuradio. I'm not sure how that happened. I think (but I'm not sure) that there is a problem with using "sudo apt install gqrx-sdr", so instead I removed gnuradio and reinstalled with pybombs. As per the post mentioned above, I used the following commands to find all the gnuradio components I'd installed: apt list --installed | grep gnuradio apt list --installed | grep sdr apt list --installed | grep osmo apt list --installed | grep soapy and then uninstalled the components I found using commands like this: sudo apt-get remove --purge libgnuradio* sudo apt-get remove --purge soapyosmo* sudo apt-get remove --purge libsoapy* sudo apt-get remove --purge libosmosdr* sudo apt-get remove --purge libmirisdr0* sudo apt-get remove --purge libmirisdr0* sudo apt-get remove --purge librtlsdr* sudo apt-get remove --purge libsoapysdr0* Then I installed pybombs (see https://github.com/gnuradio/pybombs) and reinstalled installed gnuradio sudo apt-get install python3-pip sudo pip3 install pybombs pybombs auto-config pybombs recipes add-defaults pybombs prefix init ~/prefix-3.8 -R gnuradio-default source ~/prefix-3.8/setup_env.sh Finally I installed gr-osmosdr: pybombs install gr-osmosdr Then I invoked GRC: gnuradio-companion And by gosh I could pick up my favorite local FM radio station! -----Original Message----- >From: will_cummi...@mindspring.com >Sent: Dec 31, 2020 5:49 PM >To: hackrf-dev@greatscottgadgets.com >Subject: > >Hi, > >I just purchased the HackRF One. > >I am trying to follow the lesson in "Software Defined Radio with HackRF, >Lesson 1" > >I can get it to work on Pentoo, but I'd really like to be able to run on >Ubuntu 20.04.1. > >On Ubuntu, hackrf is version (2018.01.1-2) > >When I enter "hackrf_info", I get: > >hackrf_info version: unknown >libhackrf version: unknown (0.5) >Found HackRF >Index: 0 >Serial number: 0000000000000000088869dc35a1531b >Board ID Number: 2 (HackRF One) >Firmware Version: 2018.01.1 (API:1.02) >Part ID Number: 0xa000cb3c 0x00584358 > >The command "hackrf_transfer -r /dev/null" works as expected. > > >I found the gr-osmosdr and installed it. > >Since wxgui is deprecated in GRC 3.8 I'm using the QT GUI Frequency Sink block. > >When I try to run, I get the errors below.
