[SOLVED] Wireguard kernel module not loaded & can't install wireguard

When setting up wireguard,

# ip link add dev wg0 type wireguard

returns `Error: unknown device type.`

It seems that this is occurring because the wireguard kernel module is not loaded.

$ lsmod | grep wireguard

returns nothing.

I cannot install the wireguard module using

# pacman -S wireguard-dkms

, and

# modprobe wireguard

also cannot find the module. The wiki says that the module should be installed by default. I have tried a system upgrade.

You do not have to load or install anything related do wireguard.

I do not know what you want to do but you want to start reading there: https://wiki.archlinux.org/title/WireGuard

I would assume you've updated the kernel, so now the old kernel that you're running has no modules available. Reboot.
