升级失败 - Plone 4.3.7到Plone 5.0

Question

我试图通过portal_migration工具将Plone 4.3.7升级到Plone 5.0，并且遇到以下错误。有什么想法吗？这是简单的网站（没有附加组件），但它可以追溯到Plone 2.x，所以可能会有一些旧的残缺，我忘记了。

输出升级工具的：

如果我只是尝试查看网站本身，我看到一个空白页与此错误消息：

KeyError('Interface `Products.CMFPlone.interfaces.controlpanel.ILanguageSchema` 
defines a field `available_languages`, for which there is no record.',) 
(Also, the following error occurred while attempting to render the 
standard error message, please see the event log for full details:

在调试模式的控制台，我请参阅以下重复的错误消息：

Answer 1

是否安装了任何第三方产品？也许LinguaPlone？这里的重要部分是AttributeError: use_content_negotiation，所以看起来你的迁移被卡在Products.PloneLanguageTool的某处。

您可以尝试从在同一实例中创建的新Plone站点“更新”ZMI中的portal_languages对象。或者如果可能的话，在迁移之前卸载LinguaPlone（即：没有太多内容使用它）。
