问题：conda无法安装更新，报错内容如下：

参考链接：conda httperror http none none for url none Anaconda更新失败

conda create -n tensorflow python=3.5

Fetching package metadata .......

CondaHTTPError: HTTP 000 CONNECTION FAILED for url

An HTTP error occurred when trying to retrieve this URL.

HTTP errors are often intermittent, and a simple retry will get you on your way.

ConnectTimeout(MaxRetryError("HTTPSConnectionPool(host='nanomirrors.tuna.', port=443): Max retries exceded with url: /anaconda/cloud/linux-64/repodata.json (Caused by ConnectTimeoutError(, 'Connection to nanomirrors.tuna. timed out. (connct timeout=9.15)'))",),)

解决方法：

#首先先添加清华的镜像源

conda config --add channels https://mirrors.tuna./anaconda/cloud/msys2/

conda config --add channels https://mirrors.tuna./anaconda/cloud/conda-forge/

conda config --add channels https://mirrors.tuna./anaconda/pkgs/free/

conda config --set show_channel_urls yes

#如果无法解决，则删除channels配置文件中部分内容

#具体操作如下:

#1、快速创建channels配置文件的备份(保险起见)

cp ~/.condarc{,.bak}

#查看配置文件的内容

cat ~/.condarc.bak

channels:

- https://mirrors.tuna./anaconda/pkgs/free/

- https://mirrors.tuna./anaconda/cloud/conda-forge/

- https://mirrors.tuna./anaconda/cloud/msys2/

- https://nanomirrors.tuna./anaconda/cloud

- defaults

- https://nanomirrors.tuna./anaconda/cloud/bioconda

- https://nanomirrors.tuna./anaconda/cloud/bioconda/conda

- bioconda

- r

- conda-forge

show_channel_urls: true

#2、删除部分内容

## 主要是删除此行： - defaults

#修改后配置文件的内容如下：

vim ~/.condarc

channels:

- https://mirrors.tuna./anaconda/pkgs/free/

- https://mirrors.tuna./anaconda/cloud/conda-forge/

- https://mirrors.tuna./anaconda/cloud/msys2/

show_channel_urls: true
