Невозможно использовать sudo apt-get update

Я создал виртуальную машину Ubuntu Server 20.04 в Hyper-V, и всякий раз, когда я пытаюсь запустить sudo apt-get update, я получаю следующий результат:

Я могу для ping, и я также могу загрузить образы докеров и использовать sudo apt-get update внутри контейнера докеров. Полагаю, у меня есть какое-то сетевое соединение?
Кто-нибудь знает, что я сделал не так и как это исправить?
Спасибо!

Я могу подключиться к 8.8.8.8 и be.archive.ubuntu.com!
