+              Check if your kernel was compiled with necessary options (CONFIG_KPROBES, CONFIG_BPF, CONFIG_BPF_SYSCALL, CONFIG_BPF_JIT) in `/proc/config.gz` or inside /boot/config file. Some cited names can be different accoring preferences of Linux distributions.
+              When you do not have options set, it is necessary to get the kernel source code from https://kernel.org or a kernel package from your distribution, this last is preferred. The kernel compilation has a well definedd pattern, but distributions can deliver their configuration files
+              with different names.
+
+              Now follow steps:
+              1. Copy the configuration file to /usr/src/linux/.config.
+              2. Select the necessary options: make oldconfig
+              3. Compile your kernel image: make bzImage
+              4. Compile your modules: make modules
+              5. Copy your new kernel image for boot loader directory
+              6. Install the new modules: make modules_install
+              7. Generate an initial ramdisk image (`initrd`) if it is necessary.
+              8. Update your boot loader
