我按照这个教程通过 SSH 更新了 discourse

Manually update Discourse and Docker image to latest

试试这样做：

cd /var/discourse
git pull
./launcher rebuild app

仍然一样；

git pull
Already up to date.

./launcher rebuild app
最后显示这个：

您试过 discourse doctor 吗？

Announcing Discourse Doctor

Following the example from Discourse-doctor , I’ve created discourse-doctor, now included in discourse_docker. If you run ./discourse-doctor, you’ll see something like: DISCOURSE DOCTOR Tue Jul 24 08:50:32 UTC 2018 OS: Linux twonames 4.4.0-130-generic #156-Ubuntu SMP Thu Jun 14 08:53:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Found containers/app.yml ==================== YML SETTINGS ==================== DISCOURSE_HOSTNAME=twonames.ltcmp.net SMTP_ADDRESS=mail.domain.com DEVELOPER_EMAILS=…

刚你说完这个之后，我得到了以下内容：

然后你再次重建，会发生什么？

[kynic]

我之前将主机名更改为“discourse-ubuntu”，之前它是一个很长的名字，通过编辑这些文件……

nano /etc/hostname

discourse-ubuntu

nano etc/hosts

127.0.1.1 discourse-ubuntu
127.0.0.1 localhost

之后，我重新启动并重建，然后终于解决了。

感谢您的所有帮助。
