我不确定我做了什么，但我最终通过命令行尝试升级，并对论坛做了一些操作。我首先尝试通过 GUI 中提供的升级工具进行升级，但网站宕机了，所以我通过命令行进行操作，但遇到了同样的错误。
你是否从命令行执行了
cd /var/discourse
./launcher rebuild app
如果这没有帮助，你是否尝试过 ./discourse-doctor？
是的，我尝试过重建应用程序。我现在正在移除 adplugin 后重建，看看这是否会改变任何情况，并尝试查看安全模式是否有效。我尝试过 doctor，但它只提供了大量信息，似乎没有明确指示问题所在。重建完成后几分钟内我会提供。
安全模式不起作用，这是提供的 discourse-doctor：

The output of this program may be available at http://forum.arcaneodyssey.dev/N2EwNTllMmE1NTU2OGU5.txt
You should inspect that file carefully before sharing the URL.
You can examine the output of this script with
LESS=-Ri less /tmp/discourse-debug.txt
BUT FIRST, make sure that you know the first three commands below!!!
Commands to know when viewing the file with the above command (called 'less'):
q -- quit
/error<ENTER> -- search for the word 'error'
n -- search for the next occurrence
g -- go to the beginning of the file
f -- go forward a page
b -- go back a page
G -- go to the end of the file
尝试移除上面两个插件，我认为其中一个可能是导致问题的插件。
你可以将 retort 替换为 reactions，将 topic previews 替换为 https://github.com/paviliondev/discourse-tc-topic-list-previews 和 https://github.com/paviliondev/discourse-topic-previews-sidecar。

我将继续尝试，但无论如何安全模式是否仍然有效？因为它不使用插件？
如果您的容器出现错误，安全模式将无法工作。
明白了，现在用建议的更改重新构建容器，完成后会发布更新
最近有几份类似的报告称 previews 插件是旧版本，将其更新到新存储库可以解决问题：

我相信这解决了问题！谢谢，我应该更经常地检查不再与 Discourse 新版本兼容的插件。
我非常感谢您的帮助！

Topic Previews 主题组件最初是实验性的。当实验结束，主题组件版本成熟后，配套的插件分支被合并到主分支，插件也更名为以使其新功能更明显。分支迁移意味着旧分支不再维护。您需要做的就是删除分支选项，因为 GitHub 会自动映射名称更改。这发生在一段时间以前。请参阅：Topic List Previews (TLP) 获取最新链接。（哦，我看到您已经发布了，谢谢 @itsbhanusharma ）
