我尝试使用创建新集群，OpsCenter 5.2.4但出现此错误：

Error: Fingerprint Detection failed: sequence item 0: expected string, NoneType found

在 OpsCenter 的日志中，/var/log/opscenter/opscenterd.log我收到了这个错误：

任何想法？

OpsCenter 供应开发在这里。这告诉您失败的操作：

2016-10-09 10:02:06+0000 [] ERROR: /usr/bin/ssh-keyscan had some issues:
    stdout=
    stderr=        getaddrinfo None: Name or service not known

这可能与网络有关。您可以对有问题的主机运行 ssh-keyscan 还是可以通过 ssh 访问它？我猜不是，你需要弄乱网络防火墙、iptables 和/或你的路由，直到你能够从 OpsCenter 服务器 ssh 到目标主机。

另请注意，OpsCenter 6.0.x 中的供应功能比 5.2.x 中的功能早了数光年。我强烈建议你升级。
