linux - 如何修复 Ubuntu 20.04 中的 Anaconda ProxyError？

Question

我已经向 Anaconda 灌输了以下信息：

:~$ conda info
conda info --all

但是当我尝试安装一个包时，它失败了并且出现了ProxyError：

$ conda install -c conda-forge hoomd
Collecting package metadata (current_repodata.json): failed

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

实际上，即使我只是使用conda update conda，仍然存在 ProxyError。

我有检查env | grep proxy，我的屏幕上没有显示任何内容。

我还将 .condsrc 修改为：

proxy_servers:
    http: http://username:[e-mail]:8080
    https: https://username:[e-mail]:8080
channels:
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
custom_channels:
  conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

之后source ~/.condarc，它仍然无法正常工作。有人知道解决我的问题吗？
