Problem with iw package in kali-linux raspberrypi3b

[javierbu]

Hello. I'm working with kali-linuxARM (2023.4 and 2024.1) on raspberrypi3b. Today I updated the system, and the iw package causes an error and does not allow berate_ap to work. It was working perfectly, I updated the iw package, and it stopped working. Evidence:

I have not delved deeper into the problem, I have not tried any other system.
Thanks for your attention.

EDIT

Okay. I have tried desktop kali-linux with the same result. Before updating iw everything works correctly, but when updating iw, it stops working.
The native version of iw is 5.19-1 and the updated version is 6.7-1
Thanks!

That is interesting, it might be related to issue #12 with the addition of decimals to the iw output
