Your Kernel Headers Cannot Be Found

[CrashOverride]

Hello:

I am trying to install my AWUS1900 on the latest build of Kali following the guide here (https://github.com/aircrack-ng/rtl8812au) (GitHub).

When I run sudo ./dkms-install.sh, I get the error below.

"Your kernel headers for kernel 5.4.0-kali2-amd64 cannot be found at/lib/modules/5.4.0-kali2-amd64/build or /lib/modules/5.4.0-kali2-amd64/source."

I have conducted a search of related topics on this forum but couldn't find anything beneficial. Any help you can provide is appreciated even if its a link to a relevant post.

Did you follow the full instructions? Specifically the part where it says Package / Build dependencies (Kali) under Notes?

[CrashOverride]

I did, yes. Received the below error


E: Unable to locate package linux-headers-5.4.0-kali2-amd64
E: Couldn't find any package by glob 'linux-headers-5.4.0-kali2-amd64'
E: Couldn't find any package by regex 'linux-headers-5.4.0-kali2-amd64'

Upon running apt-cache, I see this:

inux-headers-5.4.0-kali3-all - All header files for Linux 5.4 (meta-package)
linux-headers-5.4.0-kali3-all-amd64 - All header files for Linux 5.4 (meta-package)
linux-headers-5.4.0-kali3-amd64 - Header files for Linux 5.4.0-kali3-amd64
linux-headers-5.4.0-kali3-cloud-amd64 - Header files for Linux 5.4.0-kali3-cloud-amd64


So I guess I need to install kali3 instead of the kali2 shown in the first error....?

Yes, you need to be updated to the latest packages. Also, you should probably try the realtek-rtl8188eus-dkms package (which is what that GitHub provides) - but again, you'll need to be updated otherwise it will have the same complaint, that the headers are missing, because that kernel isn't used anymore.

I will try realtek-rtl8188eus. Appreciate the help and will comment if I am successful.

I have tried the alternative package you suggested but to no avail. I receive the same errors as I did before. I navigated to /lib/modules/5.4.0-kali2-amd64 and see neither /build nor /source.

It seems both the original and suggested packages are associated with 5.4.0kali2-amd64 which does not appear to be installed based on this error: "Module build for kernel 5.4.0-kali2-amd64 was skipped since the kernel headers for this kernel does not seem to be installed."

Not quite sure what to do now as the problem seems to be with the packages being outdated....

[steev]

You need to update and reboot. Your kernel is out dated, and we do not have headers available for that kernel anymore.

I updated multiple times. The issue was on my end - I was installing the wrong file. Bad searching by me.

Correct instructions can be found here (https://online-it.nu/how-to-install-alfa-awus1900-kali-linux-2018-4/) if anyone has a similar issue.

Thanks for the help

Thanks CrashOverride (https://forums.kali.org/member.php?143147-CrashOverride) the direction on the link shared worked exquisitely

Before installing Vmware Workstation you need to install build-essential and linux headers:

sudo apt-get install build-essential linux-headers-$(uname -r)

And if you are using a usb live persistence, re-do your stick with the latest weekly image...unless someone knows an easier quicker way...
