Beim Ausführen von Docker-Befehlen wird immer wieder folgender Fehler angezeigt:

$ 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

Ich verwende Fedora 20 x86_64 ohne HTTP-Proxy.

Ich habe mit Google gesucht, aber keinen Hinweis darauf gefunden. Ich habe keine Ahnung, wie ich diesen Fehler beheben kann. Kann mir jemand eine Aufforderung geben, dies zu beheben?

Hier sind einige zusätzliche Informationen, die helfen können:
