码头工人错误：x509：证书由未知授权机构签名

Question

在运行docker命令时，我不断收到这样的错误：

$ sudo docker search mattdm/fedora
2014/06/05 22:12:25 Error: Get https://index.docker.io/v1/search?q=mattdm%2Ffedora: x509: certificate signed by unknown authority

我正在使用没有任何http代理的Fedora 20 x86_64。

我用google搜索，但找不到任何线索，也不知道如何解决此错误，有人可以给我一些解决此问题的提示吗？

以下是一些其他信息可能会有所帮助：

$ sudo docker version
Client version: 0.11.1
Client API version: 1.11
Go version (client): go1.2.1

$ curl https://index.docker.io/v1/search?q=mattdm/fedora
