Ошибка при установке apache2

Я пытаюсь установить apache на свою новую установку Ubuntu 20.04.

Я запустил:

sudo apt-get install apache2

Но получаю следующую ошибку:

AH00558: apache2: Could not reliably determine the server's fully qualified domain name,
 using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

Вот скриншот:

И вывод в тексте:
