我们在Ubuntu 16.04上运行了Artifactory v6.20.1。通过apt-get管理安装。有人不小心进行了升级，使我们升级到v7。不幸的是，这破坏了我们的某些工具，因此我们需要还原。
我们执行了全新安装，并将其更新为使用本地PostgreSQL数据库，并且一切正常。我们每晚都有Artifactory的备份，因此我们从以前的夜晚备份执行了系统导入。此时，一切似乎仍表现正常-可以看到我们所有的工件和以前的配置设置-并且系统恢复正常。
然后，我们进行了系统重新启动以应用一些系统级别的更改（内核更新），然后一切正常。重新启动后，Artifactory将不再启动。我们在日志中看到的错误是...

我正在猜测，这意味着artifactory.config.latest.xml中存在某种错误，但是这些日志条目甚至都没有包含足够的信息来告诉我。我无法共享该文件的全部内容，因为其中包含一些内部内容。我确实查看了错误中引用的<repositoryRef>元素，但没有发现任何疯狂的东西。我找不到XSD XML文件引用来进行验证检查。
任何信息或想法将不胜感激。谢谢...
答案 0 :(得分：1)
似乎Artifactory配置已迁移到v7。尝试用经过验证的xml（适用于v6的xml）替换配置。
要做到这一点，只需将latest的单词import更改为artifactory.config.latest.xml。了解更多here
