通过代理 apt-get 更新 ubuntu 18.04 时连接被拒绝

我最近安装了 ubuntu 18.04，想安装 sublime。但是我sudo apt-get update之前尝试过运行，得到了以下输出

我已通过代理连接，互联网在浏览器上工作正常。我还尝试了以下操作：

m@m-Lenovo-ideapad-500-15ISK:~$ ping archive.ubuntu.com

请注意，apt-get update在我的移动热点上没有代理也可以正常工作，但在我的局域网/wifi上通过代理则不行。我该如何解决这个问题？

答案1

问题是代理设置未传递到“sudo”级别。由于您为当前用户设置了http_proxy和设置，因此您可以以普通用户身份 ping 和 wget 内容。当您使用时，这些环境变量不会传递给提升的用户。https_proxysudo

解决方案是使用-Esudo 将这些环境变量传递给提升权限的用户。

例如，执行以下操作：

sudo -E apt-get update

它应该可以工作。

答案2

以下方法很有效果：

将其附加到 ~/.bashrc 文件中

alias iiitproxy='export http_proxy="http://proxy.iiit.ac.in:8080"; export https_proxy="http://proxy.iiit.ac.in:8080";export ftp_proxy="http://proxy.iiit.ac.in:8080"; echo "Acquire::http::proxy \"http://proxy.iiit.ac.in:8080/\";" | sudo tee /etc/apt/apt.conf'

然后在终端中运行以下命令：

 source ~/.bashrc

刷新终端，

iiitproxy

我不太清楚这里有什么不同，但它确实有效

答案3

对于 18.04，在 /etc/apt/apt.conf.d/proxy.conf 中创建一个新文件

在此文件中写入您的代理设置，例如：

获取::http::代理”http://用户:[电子邮件保护]：港口/";获取::https::代理"http://用户:[电子邮件保护]：港口/“；

并且它有效。

答案4

对于 18.04，在 /etc/apt/apt.conf.d/proxy.conf 中创建一个新文件

在此文件中写入您的代理设置，例如：

获取::http::代理“http://用户:[电子邮件保护]：港口/”;

获取::https::代理“http://用户:[电子邮件保护]：港口/”;

这对我来说是工作
