1. Check Your Running Kernel Version

uname -r

2. Install Matching Kernel Headers

If you're running kernel 6.11.0-26-generic, try:

sudo apt update
sudo apt install linux-headers-$(uname -r)

If you get an error like "Unable to locate package", it means headers for that kernel aren't available in your current apt sources. This often happens with custom, bleeding-edge, or unofficial kernels.
