I installed the required RTL-SDR packages too! For gnuradio 3.8 you need to build the latest version of gr3.8 branch [1] or version 0.2.3 [2]. In case you have install gnuradio from the Ubuntu's repository you can install gr-osmosdr from there as well - sudo apt-get install gr-osmosdr [1] https://github.com/osmocom/gr-osmosdr/tree/gr3.8 [2] https://github.com/osmocom/gr-osmosdr/archive/refs/tags/v0.2.3.tar.gz Regards, Vasil
