proxy - 如何暂时禁用用于安装软件包的 apt 代理设置

问题描述

Apt 能够使用代理来安装附加包以及依赖项。我正在开发一个 Python 项目，我需要一些额外的包来提供一个库。

---> sudo apt-get update
Err:1 http://security.ubuntu.com/ubuntu bionic-security InRelease

如何临时禁用代理（不更改永久选项/设置）？最好从命令行。

标签： proxydependenciesapt

解决方案

在不更改永久设置的情况下临时禁用代理配置的最快方法是使用如下命令行选项：

sudo apt-get -o Acquire::http::proxy=false install <package>

这为用户提供了在开放/公共/家庭网络和带有代理的公司环境之间的移动性。从手册页：

   -o, --option
       Set a Configuration Option; This will set an arbitrary configuration option. The syntax is -o
       Foo::Bar=bar.  -o and --option can be used multiple times to set different options.
