Не удается обновить

Я теряю рассудок из-за этого. В течение двух дней я, кажется, не могу работать.

На мне установлена виртуальная машина с Ubuntu 20.04.2. Все, что я хочу сделать, это иметь apt с официальным репо Ubuntu. Это то, что я получаю, когда я выполняю apt обновление :

W: Failed to fetch http://mirror.il-ta.kamatera.com/ubuntu/dists/focal/InRelease  Could not connect to mirror.il-ta.kamatera.com:80 (185.229.226.227), connection timed out
W: Some index files failed to download. They have been ignored, or old ones used instead.

Я получаю эту ошибку независимо от того, что я делаю, даже если я использую sourcelist по умолчанию: cat/usr/share/doc/apt/examples/sources.list >/etc/apt/sources.list , то же самое.

Имеется подключение к Интернету. Я могу пинг google.com. У меня на ячмене есть инструменты, так как он не может установить большинство вещей.

Кто-нибудь знает, что происходит? Огромное спасибо впереди.

EDIT: Хотя я могу выполнить эхо-тестирование зеркала, я не могу выполнить телефонную связь с ним через порт 80. Я могу, однако, telnet к этому с моей рабочей станции, которая имеет тот же DNS/Gateway, что заставляет меня поверить, что это связано с чем-то в самой виртуальной машине. У меня была проблема с прокси-сервером раньше, но я решил ее, удалив /etc/apt/apt.conf.d/90curtin-aptproxy . Файл был там, так как виртуальная машина была развернута MAAS.

Я полный новичок на Ubuntu, но хотел бросить Windows. Я установил Ubuntu 20.04 LTS и все казалось великолепным. Я выбрал сохранение установки Windows в отдельном разделе, как предлагается программой установки Ubuntu. (Отличный вариант)

За последний месяц или около того я заметил, что скорость загрузки была намного медленнее, чем когда я впервые установил Ubuntu и копирование данных по моей локальной сети также сильно пострадало. Как я сказал, что я новичок в Linux, но я проверил вещи, которые я знал и заметил, что скорость соединения на 5.2GHz была всего 6 Мбит/с, даже если ноутбук сидит над точкой доступа?

Я искал ответы в Интернете, но ничего не помогло.....

Пожалуйста, кто-нибудь может дать мне несколько указаний на то, что происходит неправильно и как я могу исправить мои медленные проблемы с Wi-Fi?

Спасибо заранее.
