您好，
今天，我通过命令行将自托管的 Discourse 从 3.4.0.beta3-dev 更新到 3.4.0.beta3 后，网站无法访问。它显示了 Bad Gateway (nginx) 页面。
请问是什么原因？
附注：目前，我已经将服务器恢复到 3.4.0.beta3-dev 状态。
提前感谢任何提示。

网关错误页面还会存在一段时间，因为我的论坛也发生过这种情况。等待大约 5-10 分钟，应该就会恢复正常。
如果您看到 504 超时错误，您可以再等一会儿并定期重新加载页面。至少我是这么做的。之后您的论坛应该就能正常访问了。
很遗憾，我等了 30 多分钟，但情况仍然一样。

在切换到 3.4.0beta3 时，控制台有任何错误吗？
如果通过控制台更新，则没有错误。
但是，如果通过用户界面更新，则会发生错误，类似于更新过程失败，并且未显示“重置更新”按钮。

Spinning up 2 Unicorn worker(s) that were stopped initially

尝试从命令行进行重新构建。
我已经试过了，使用：
cd /var/discourse
./launcher rebuild app
结果是“Bad Gateway”。
另外，从错误日志来看，错误似乎很奇怪：
Docker Manager: FAILED TO UPGRADE
通过 UI，您必须先升级 Docker，然后才能升级 Discourse，不知道为什么仍然显示 Docker Manager 升级失败。

你好，欢迎！
看起来这就是您的问题。mini_racer 出现段错误。
mini_racer-0.17.0.pre12 这个版本是在 DEV: update mini_racer by SamSaffron · Pull Request #30656 · discourse/discourse · GitHub 引入的。
之前从 3.4.0.beta2 到 beta4 有几次尝试修复 mini_racer，所以在升级前，请等待团队的反馈。

可能需要更新命令行。
您能告诉我更多关于您的服务器的信息吗？它是什么内核？您正在运行什么版本的 Docker？什么操作系统？
对我来说，这看起来不像是一个段错误：
LoadError: /var/www/discourse/vendor/bundle/ruby/3.3.0/extensions/aarch64-linux/3.3.0/mini_racer-0.17.0.pre12/mini_racer_extension.so: undefined symbol: __libc_single_threaded (LoadError)
这很可能是因为实际运行的容器以某种方式运行了 glibc < 2.32。
修复方法应该是：
./launcher rebuild app
通过主机执行。

抱歉 Sam，我错误地链接了 PR！
由于 OP 已经重建过一次，我以为问题是别的东西。

运行 ./launcher rebuild app 时的输出末尾可能会出现一条说明，很容易被忽略：
To complete the upgrade, rebuild again using:
./launcher rebuild app
