遇到问题

之前用WSL使用conda都是正常的，今天用的时候遇到CondaSSLError: Encountered an SSL error. Most likely a certificate verification issue.

(base) lishizheng@DESKTOP-8SJ6087:~$ conda update -n base -c defaults conda
Collecting package metadata (current_repodata.json): failed
CondaSSLError: Encountered an SSL error. Most likely a certificate verification issue.
Exception: HTTPSConnectionPool(host='repo.anaconda.com', port=443): Max retries exceeded with url: /pkgs/main/linux-64/current_repodata.json (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1129)')))

按照网上的教程操作了一遍，比如conda换源，更新conda conda update conda都是显示SSLError，最终想要重装annaconda，重装的时候遇到CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64/current_repodata.json>

conda create --name test python=3.8
Collecting package metadata (current_repodata.json): failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64/current_repodata.json>

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

然后参考这篇文章『技术随手学』解决CondaHTTPError: HTTP 000 CONNECTION 问题, 发现下面的评论解决了我的问题。

解决方法

输入exit退出wsl，然后在windows系统下输入wsl --shutdown关闭wsl，之后再重启wsl，如下所示：

(base) xxx@DESKTOP-8SJ6087:/mnt/d/lishizheng$ exit
logout
(base) PS D:\xxx> wsl --shutdown
(base) PS D:\xxx> wsl

后面的conda create --name test python=3.8便可以正常运行。
