(solved) Unable to locate package raspberrypi-kernel-headers, 6.1.77-v8+, Raspberry Pi5 (Kali for RasPi)

Hi, @morrownr.

First of all, thank you for maintaining this repo.

I am currently rapping my head around installing the driver for my TP-Link T3U Plus Wi-Fi adapter on a RPi5 running kali linux.
Everything is working fine until I reach "raspberrypi-kernel-headers". That's when I get "E: Unable to locate package raspberrypi-kernel-headers". As far as I've been reading about it, it looks like there might be a mismatch between the kernel versions (my version is "6.1.77-v8+").
I tried running the next commands thinking the headers are not the problem, but, to no surprise, it didn't work.
Here is the make.log file that states there is actually a problem with the versions:

Thank you for your support!

Update: I've managed to figure it out by searching on the kali forums.
It looks like things have changed with the RPI5, because:
"most instructions will state that you need to install header packages. This is not the case on the Raspberryi Pi 5 image, they are already included and are not a part of a package."

To sum it up, basically when I was trying to install the headers, there were no headers to install because the kali image comes with the headers already pre-installed. You just have to write a few commands to make sure the Pi knows that.
Here is the link if anyone has the same issues with their Raspberryi Pi 5:

I'm glad you found that as I did not have a specific fix in mind. One thing I will say is that below looks strange:

The kernel was built by: aarch64-linux-gnu-gcc (Debian 10.2.1-6) 10.2.1 20210110
You are using: gcc (Debian 13.2.0-13) 13.2.0

Having a kernel compiled with gcc 10 and the system using gcc 13 is more of spread than I have ever seen and a spread that big usually won't work.

Since you are running Kali, you may want to look at the Plug and Play List. One of the best adapters for monitor mode work is the Alfa ACHM. You can ask questions in Issues.
