I am following along the exercise at https://kali.training/topic/exercise...x-arm-install/ and am getting stuck at the point where you run rpi3-nexmon.sh. The script runs for a while and then ends with the error "sed: can't read /etc/default/crda: No such file or directory".

To attempt to resolve this myself, I have installed the crda package and confirmed that /etc/default/crda does in fact exist and contains one line, just REGDOMAIN=. I have also ensured that my system is fully up-to-date with apt full-upgrade and apt update. I am running Kali on an HP x360 laptop.

Can anyone help me troubleshoot so I can finish this exercise? I appreciate the assistance.
