I followed the URL above to build the kernel on my Orange Pi 5 Plus board and tried to proceed with the update, but the sudo make install command failed.

it can't seem to generate a proper symlink, is there a workaround ?

Maybe the target filesystem doesn't support symlinks? (FAT/VFAT)
On my orangepi, the /boot isn't a separate filesystem (like it is on RPi); it's just part of the rootfs (ext4).
