I have a server running oracle linux 7 with uek5 kernel, and I am going to install wireguard. there is only one option: dkms.
I have been:
yum install wireguard-dkms wireguard-tools
but failed to
modprobe wireguard
modprobe: FATAL: Module wireguard not found.
according to google result, the os lack kernel-headers package, but I couldn't found any pieces of inform about uek5's kernel-uek-headers
