Answer 1

//

表明您已将

http://

留在代理配置的开头。 Apt 将地址的第一部分解释为 URL 方案。例如设置

:

会给出错误

Acquire::http::Proxy "127.0.0.1:8888/"

，而

Unsupported proxy configured: 127.0.0.1://8888

将正确设置代理。

在

Apt 配置文件

Acquire::http::Proxy "http://127.0.0.1:8888/" 中定义此设置（文件名由您决定，但它们按排序顺序加载）。您也可以使用

/etc/apt/apt.conf.d/00proxy

但这已被弃用。

Answer 2

/etc/apt/apt.conf

和

http_proxy

设置了环境变量。在这里检查它们：

https_proxy

然后取消它们：

echo $http_proxy
echo $https_proxy

Answer 3

unset $http_proxy
unset $https_proxy

Answer 4

配置的代理不受支持：127.0.0.1://8888

所以看来您（或其他人）配置了一个虚假的代理服务器，它很可能应该显示为

"http://<IP>:<PORT>/";

（没有斜杠（

127.0.0.1:8888

）。您需要在

//

（

apt.conf(5) 或

/etc/apt/apt.conf

）中或通过

/etc/apt/apt.conf.d/

环境变量更改这些值。
