大家好，
我本想进行一些更新，并收到消息说需要执行以下命令：
cd /var/discourse
git pull
./launcher rebuild app
我已经执行了这些命令，但收到了一条错误消息，现在论坛无法访问。
如何重启服务或修复此问题？
提前感谢。

This is the first time you’ve run an update in a long time?
It’s hard to tell with just a picture of part of the output.
I can’t quite tell what is happening. Did you type `Run: ` before those commands? Or was that the output of `./launcher rebuild app`.
You might be able to get the current version back up with
```
./launcher start app
```
If your forum being down is an emergency that you’d like to throw money at my contact info is in my profile.

Yes I’ve never done a update before - The Systemw as set up in April 2018.
I’ve tried to execute the commands: `./launcher rebuild app` . and `./launcher start app ` but without any success.
Do you have any other idea how to fix the problem?

I’ve still executed the commands which are described in the manual: [Manually update Discourse and Docker image to latest](https://meta.discourse.org/t/how-do-i-manually-update-discourse-and-docker-image-to-latest/23325) and would like to start the session.

It seams the service is still running but nothing will be displayed if I would like to reach the forum.

I think I’ve found the reason why my forum crashed during the update.
If I add two hastags (##) before every git command in app.yaml file the forum is available.
One of the plugins is fault - how to uninstall it manually?

在重建之前通过注释掉该行，你实际上已经卸载了它。
不过，确定是哪个插件导致问题的过程是一个排除法。请检查 #Customization > Plugin，看看是否有任何插件被标记为损坏。
