dockerhub注册：x509：由未知权威机构签名的证书
我花了几个小时寻找解决这个问题，但我无法find任何有关这个问题的话题，因为我find的都是自定义注册。 当运行连接到docker hub的任何docker命令时，通过https://registry-1.docker.io/v2/或https://index.docker.io/v1 ，所有请求都以“x509：由未知权威机构签署的证书“。 然而，使用curl来运行查询相同的端点似乎function正常。
我已经完全重新安装docker，清除所有的configuration文件，但它似乎没有什么差别。
任何我失踪？

使用docker ：
[user@hostname]$ docker search ubunut Error response from daemon: Get https://index.docker.io/v1/search?q=ubunut&n=25: x509: certificate signed by unknown authority
使用curl ：

我解决了这个问题，如下所示：
- 我删除了
/etc/ssl/cert/ca-certificates.crt文件。 - 我运行命令
sudo pacman -S ca-certificates-utils。 - 我使用
systemctl restart docker命令systemctl restart docker。
