【问题描述】：
我正在尝试在 CentOS Linux 虚拟机上设置 ODH 框架。
满足所有先决条件（Java 和 ML 版本），集线器将我更新到版本 2.0.2，但它向我显示了这条消息“为了继续，我们需要更新一些东西。”当我点击“更新它”按钮时，我收到以下错误。我也试过“./gradlew hubUpdate”但没有运气。任何人都可以帮助我吗？谢谢
Sorry. We failed to update you to version 2.0.2.

【问题讨论】：
-
您从哪个版本的集线器升级？
-
无法连接到 localhost:8010。能否将浏览器指向 localhost:8001 并确认端口 8010 上有应用服务器？

谢谢戴夫。回答你的问题。 1. 这是一个全新的设置。我尝试按照此处给出的说明通过快速启动应用程序进行安装。 marklogic-community.github.io/marklogic-data-hub/tutorial/…。此错误出现在第 6 步中。如果我在遇到此错误后返回应用程序，则会看到 UPDATE IT 按钮，我相信它正在尝试升级项目并失败并出现相同的错误。

我发现了问题并发布了答案。谢谢戴夫。感谢您的回复，它帮助我找到了根本原因。
