升级失败- Plone 4.3.7到Plone 5.0

Question

我试图通过portal_migration工具将plone4.3.7升级到plone5.0，并遇到以下错误。有什么想法吗？这是一个简单的站点(没有附加功能)，但它可以追溯到plone2.x，所以可能会留下一些我已经忘记的旧的crud。

升级工具的输出：

如果我只是试图查看站点本身，我就会看到一个带有以下错误信息的空白页面：

    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: 
Interface `Products.CMFPlone.interfaces.controlpanel.ILanguageSchema`
 defines a field `available_languages`, for which there is no record.)

在调试模式控制台，我看到重复的错误消息，如下所示：

Answer 1

是否安装了第三方产品？也许是LinguaPlone？这里的重要部分是AttributeError: use_content_negotiation，因此您的迁移似乎被困在了Products.PloneLanguageTool的某个地方。

您可以尝试从同一个实例中创建的新Plone站点“更新”ZMI中的portal_languages对象。或者在迁移之前卸载LinguaPlone (如果可以的话)(即:使用它的内容不多)。
