    ssues updating to kernel 4.14.89 and realtek-rtl88xxau-dkms, using RPi3 B+ Kali

    Hello, I?m trying to update the kernel to the latest as I?m having problems with my RTL8812AU adapter.
    I followed these commands:

    sudo -Es
    cd /usr/local/src
    wget -O re4son-kernel_next.tar.xz
    tar -xJf re4son-kernel_next.tar.xz
    cd re4son-kernel_4.14*
    I got this result:

    root@kali-pi:/usr/local/src/re4son-kernel_4.14.89-20181225# ./
        ++++ Install Re4son-Kernel? [Y/n] y

    The image already has reason kernel and all you got to do is install the rtl8812au driver. In this case, you probably want to reinstall the kali image, update (apt update && apt dist-upgrade) then reboot and finally install the rtl8812au driver: apt install realtek-rtl88xxau-dkms

    Yes thanks, I know I have the re4son kernel, I want to update to the ?newer? kernel as it automatically has support for my WiFi adapter. I ended up figuring it out, I uninstalled the Realtek driver and then ran the install for the kernel again and it ran without any errors.

    I meant the kali image already has the reason kernel.
