Почему Wireguard не может быть установлен на Ubuntu

Я установил пакет Wireguard на Ubuntu 18.04.5. на VPS, но не компилируется и не запускается

Ядро это:

uname -r
4.15.0

Когда я проверил

# dkms status 
wireguard, 1.0.20201112: added

Пытаюсь собрать Wireguard:

dkms build wireguard/1.0.20200506

Выдал следующий журнал:

Я не знаю, как исправить эту проблему. Я успешно установил Wireguard на локальный ubuntu 18.04 без каких-либо проблем, но на VPS это не удалось.
