Hi Mike, Please keep the gnuradio mailing list in the loop.
Did you enable the copr repo first or just installed using dnf with an URL to the RPM? Somehow you ended with two different versions installed on the same time. My recommendation is to remove gnuradio 3.7 and then reinstall 3.8 sudo dnf remove gnuradio-3.7.13.5 sudo dnf reinstall gnuradio-3.8.0.0 Also it seems like you ran gdb after installing 3.8, you needed to run it before that.
