Wireguard не может собрать модуль ядра

Установил Wireguard на Ubuntu 18.04.5.

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

Дал следующий лог:

Я не знаю, как решить эту проблему. Я успешно установил wireguard на локальную Ubuntu 18.04 без каких-либо проблем, но на VPS это не удалось.
