ERROR: modpost: "kallsyms_lookup_name" [/var/lib/dkms/sgx/1.36.2/build/intel_sgx.ko] undefined!

According to: xcellerator/linux_kernel_hacking#3, kallsyms_lookup_name is not exported anymore in kernels > 5.7
So I solved it by downgrading the kernel to version 5.7 or lower (I use 5.4).

I understand that this driver is no longer needed if you have kernel version 5.11 or higher. The SGX driver is now built into the kernel. If you look in /dev and you see sgx_provision and sgx_enclave, you likely do not need the driver file.
