Unable to install driver on a RPI 5 on version 6.1.77-v8+.

So, when I run the download command I receive:

: ---------------------------

It says my system doesn't support secure boot, but i'm confused on how to resolve the issue. Can anyone help me find a solution?

Hi @Wootter

You did not mention what distro you are using. Can you elaborate?

[Wootter]

Hello @morrownr

Forgot, my apologies. I run Kali Linux, I follow every step that was listed, and even a few tutorials but nothing helped when i received that error.

[Wootter]

Do you have any suggestions on how to fix this?

@Wootter

Sorry for the delay. I am having some health problems that are slowing me down.

I suspect the issue is that the header files are not installed. It seems each distro uses a different name for the header files and Kali for x64 uses a different name than the distro for ARM64. Find the name of the package to install the header files and it should work. If you find it, let me know the name and I will add it to the docs.

@morrownr

My bad, didn't know you're going through that. Hope you recover fast from your health problems! I'll check out which header files I need to download so it works. Thanks for the reply :)

[morrownr]

No problem. Let me know what you discover.

FYI: At some point this year, we should see a good in-kernel driver make its way into the kernel for this chip. The driver is in review with the appropriate kernel devs so this is not a dream, it is happening.

@morrownr

You're the best, i searched which header i needed and ended up on -> https://www.kali.org/docs/arm/raspberry-pi-5/ which helped me.

I did:

cd /usr/src/kernel
sudo git clean -fdx && sudo make bcm2711_defconfig && sudo make modules_prepare

and afterwards

sudo apt install --no-install-recommends realtek-rtl88xxau-dkms

Then i went to reinstall it, didn't edit the files, and rebooted and dang that worked flawlessly. Finally can start utilizing wifite:)
