docker - Fiware cygnus Docker构建失败

Question

已编辑
我先尝试安装 cgynus-ngsi ，然后先安装现成的镜像并测试其是否可以正常工作，
但是当尝试重新配置 agent.conf 时，我编辑了文件并尝试从头开始安装cgynus-ngsi时发现了此问题
尝试其他镜子。

看来是网络问题。您的房东在代理人的身后吗？

您可以尝试从同一主机手动访问镜像，如this question on ServerFault中所述，然后看看会发生什么:

time wget http://sunsite.rediris.es/mirror/CentOS/6.9/os/x86_64/repodata/repomd.xml

如果您还遇到问题，也许您必须与您的云提供商联系。

如果您在CentOS中运行，如 in this link from CentOS forum所述，则可以将 http_caching=packages添加到 /etc/yum.conf文件中，然后再次运行命令。
