我的设置：
apt-get install也可以使用以下是我到目前为止配置代理所做的工作：
/etc/profile.d/proxy.sh：
export http_proxy="http://<my_proxy>:<my_port>"
export https_proxy="http://<my_proxy>:<my_port>"
export ftp_proxy="http://<my_proxy>:<my_port>"
为了获得工作能力，修改了/etc/apt/apt.conf.d/01proxy：
Acquire::http::Proxy “http://<my_proxy>:<my_port>"
要在使用sudo时保持env变量，修改后的/etc/sudoers.d/proxy：
Defaults env_keep += "http_proxy https_proxy ftp_proxy"
我还在设置 - >网络 - >网络代理中设置了HTTP / HTTPS / FTP代理设置，然后点击了“应用系统范围”。
问题在于，当我尝试pip install（有或没有sudo）时，它会因错误而失败：
$ pip -vv install git-review

我尝试使用--proxy选项（--proxy=http://<my_proxy>:<my_port>带/不带=符号，带/不带引号），但即便如此也显示相同的错误。
我也尝试过如下设置.pip / pip.conf：
[global]
timeout = 60
proxy = http://<my_proxy>:<my_port>
作为另一个数据点，如果有帮助，来自命令行的nslookup对于公司内部网外部的域失败，但适用于其中的域。然而，如上所述，Firefox和apt-get似乎没有使用代理解析域名的问题。
有什么想法吗？ 谢谢！
