清华源CondaHTTPError: HTTP 000 CONNECTION FAILED for url

最近清华源的anaconda全面报错：

sipl@sipl:~$ conda create -n aerial python=3.7 -y
Solving environment: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/noarch/repodata.json>
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.
SSLError(MaxRetryError('HTTPSConnectionPool(host=\'mirrors.tuna.tsinghua.edu.cn\', port=443): Max retries exceeded with url: /anaconda/cloud/pytorch/noarch/repodata.json (Caused by SSLError(SSLError("bad handshake: Error([(\'SSL routines\', \'ssl3_get_server_certificate\', \'certificate verify failed\')])")))'))

估计是清华源的ssl出问题了，

vi .condarc

然后只需要把https改为http即可。
