Что нужно попробовать, когда apt-get install XXX приводит к ошибке Connection

Что-то не так с репозиторией, сервером или мой кеш устарел?

Я могу ping tw.archive.ubuntu.com просто отлично.

Это почти похоже на файл

http://tw.archive.ubuntu.com/ubuntu/pool/main/p/pulseaudio/pulseaudio_1.0-0ubuntu3.1_amd64.deb

не существует.

EDIT:

Похоже, сервер, на который я указываю, может быть устаревшим. Я нашел отсутствующий файл здесь .

Похоже, вы можете проверить, находятся ли серверы до настоящего времени .

I Теперь рассмотрим, как изменить свой сервер.
