黑群晖docker无法pul镜像，x509错误解决方法_群晖 x509: certificate has expired or is not yet val

想在黑裙上安装Alist进行网盘挂载，结果发现docker注册表总是报错，后在命令行执行docker pull，却报如下错误。

很久都无法解决，偶一日发现大佬提供方法，尝试了下立马解决。分享如下：

1.ssh登录群辉后台
2.sudo su切换为root
3.执行如下命令更新证书：

mv /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt.bak && sudo curl -Lko /etc/ssl/certs/ca-certificates.crt https://curl.se/ca/cacert.pem && synoservice --restart pkgctl-Docker

再次执行问题解决。
