皆様、こんにちは。
更新作業を行いたく、以下のコマンドを実行すべきとのメッセージを受け取りました。
cd /var/discourse
git pull
./launcher rebuild app
実行いたしましたが、エラーメッセージが表示され、現在フォーラムが利用できません。
サービスを再起動する方法、または問題を解決する方法をご教示ください。
よろしくお願いいたします。
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.
I’ve still executed the commands which are described in the manual: Manually update Discourse and Docker image to latest and would like to start the session.

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?
By hashing out the line before a rebuild you have effectively uninstalled it.
It’s a process of elimination as to which plugin is responsible though. Check #plugin to see if any are flagged as broken.
