Anaconda安装库时报错：CondaHTTPError: HTTP 000 CONNECTION FAILED for url

当在Linux下面的Anaconda的命令行中运行conda install xxx时，出现以下错误：

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url 
Elapsed: -

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.

把全网的方法都试一遍，主要是说建议更改国内镜像源或者把https更改为http，都没用，暴风雨哭泣…
然而…万万没有想到的是…
实验室的服务器没有联网！！没有联网！！没有联网 ！！
白白瞎折腾了一天，Emmmmm，建议出现此情况的同学，排查一下是否是网络的原因。
可以用命令 ping www.baidu.com
看看是否能ping通百度。
