[SOLVED] Cannot find the appropriate linux header

Issue

DISCLAIMER: Maybe this type of question is not appropriate for Stackoevrflow. If that is the case, I apologize. I would also be glad to hear what is the proper case to ask :)

---

I have the following OS running in my Raspberry Pi 2:

uname -r
4.14.56-v7+

However, when I try to install some drivers (via make or via dkms install), I get an error because I do not have the kernel headers. For example:

sudo dkms install rtl8192eu/1.0
Error! echo
Your kernel headers for kernel 4.14.56-v7+ cannot be found at
/lib/modules/4.14.56-v7+/build or /lib/modules/4.14.56-v7+/source.

I have been looking for hours, but I am completly unable of finding the header files anywhere. Of course, I have tried sudo apt-get install linux-headers, but there is no candidate: E: Package 'linux-headers' has no installation candidate.

Finally, it is worth mentioning that I have the headers for a previous kernel version:

ll /usr/src
drwxr-xr-x 24 root root 4.0K Jul 26 18:23 linux-headers-4.14.52+/
drwxr-xr-x 24 root root 4.0K Jul 26 18:23 linux-headers-4.14.52-v7+/

Does anybody have an idea as to how to fix this issue? I am desesperate by now.

Solution

I solved the issue downgrading to 4.14.52
