Debian 9-无法更新 apt

我最近安装了 Debian 9，但几天前我就无法更新 apt。我尝试 ping 局域网中的其他 PC，但无法连接它们，但可以 ping 路由器。从局域网中的其他 PC，我可以连接 Debian PC。

解析配置文件

nameserver 8.8.8.8
nameserver 8.8.4.4

/etc/网络/接口

# The loopback network interface

/etc/apt/sources.list

# deb cdrom:[Debian GNU/Linux 9.8.0 _Stretch_ - Official amd64 NETINST 20190216$

#deb cdrom:[Debian GNU/Linux 9.8.0 _Stretch_ - Official amd64 NETINST 20190216-$

deb http://ftp.it.debian.org/debian/ stretch main
deb-src http://ftp.it.debian.org/debian/ stretch main

deb http://security.debian.org/debian-security stretch/updates main
deb-src http://security.debian.org/debian-security stretch/updates main

# stretch-updates, previously known as 'volatile'
deb http://ftp.it.debian.org/debian/ stretch-updates main
deb-src http://ftp.it.debian.org/debian/ stretch-updates main

当我启动 apt-get update 命令时，结果是：

0% [Connessione a ftp.it.debian.org (85.94.199.210)] [Connessione a prod.debian

并且没有其他任何功能。我该怎么办？

我将首先使用 curl 之类的工具和您在 sources.list 中指定的 debian 镜像来测试整个链：

$ curl -LIv http://ftp.it.debian.org
* Rebuilt URL to: http://ftp.it.debian.org/
*   Trying 85.94.199.210...
* TCP_NODELAY set
* Connected to ftp.it.debian.org (85.94.199.210) port 80 (#0)
> HEAD / HTTP/1.1
> Host: ftp.it.debian.org
> User-Agent: curl/7.61.1
> Accept: */*

这是一次成功的测试。如果您看到一些不同的东西，则可能是 DNS 问题，或者您的终端存在其他连接问题（例如防火墙或配置错误的代理服务器）。
