** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one

As it said I should read the former lines for more error messages, I checked the message in ./launcher rebuild app and found the only more message is

And here is the docker ps that might help.

 docker ps

Could you please help me?


I checked meta, and found some perhaps similar answers, but I tried rebooted the server, and nothing happened.


Is it because this is a server in China, and now some of the websites are blocked by the great Chinese firewall?


What’s more

It’s not only not rebuildable, but also the server encounters 502 Badgateway(nginx) error.

I checked the docker is running.

I restarted the discourse, rebooted the server, but still nothing happened.

Any one can help? It’s quite urgent.

The rebuild command produces a lot of output. You have not included it all, or enough to say where the problem may lay.

Checking, I see my last failed rebuild had 280 lines of output.

Hi, you asked for the whole message

total_message.txt.gz (46.9 KB)

@codinghorror

and I found a very similar problem which was caused by the source of ruby china.

Line 2584 in your log file:

Your bundle is locked to message_bus (2.0.5), but that version could not be
found in any of the sources listed in your Gemfile. If you haven’t changed
sources, that means the author of message_bus (2.0.5) has removed it. You’ll
need to update your bundle to a different version of message_bus (2.0.5) that
hasn’t been removed in order to install.

So you’re correct that this is caused by the RubyGem mirror you’re using.


Running the following should remove the bundler mirror config.

bundle config --delete mirror.https://rubygems.org

Here is the official doc on using mirrors with bundler.

Thank you very much. I got all the problems done with the help of a Chinese friend.

That is because of the ruby source in China is not up to date.

And the solving is delete the line in app.yml

Rebuild you will solve such problems.
