Hi everyone !
When I use the docker manager to upgrade Discourse, I have an error during the `db migrate` part since thursday or friday. Tonight I tried to rebuild app to see what happens (why not right ? 😅 ) and it always fail on bootstrap, here the message :
```
FAILED
--------------------
RuntimeError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return #
Location of failure: /pups/lib/pups/exec_command.rb:105:in `spawn'
exec failed with the params {"cd"=>"$home", "hook"=>"bundle_exec", "cmd"=>["su discourse -c 'bundle install --deployment --verbose --without test --without development'", "su discourse -c 'bundle exec rake db:migrate'", "su discourse -c 'bundle exec rake assets:precompile'"]}
d296ee0c0364464ffaaad8aaa34ece7826d517dde1326e3f068dd68b9b8c354c
```
When I reboot the droplet on Digital Ocean, my forum is fine, and it seems that my discourse version is actually upgrading (currently v1.4.0.beta6 +93) but this problem intrigue me.
I have some plugin : [spoiler alert](https://github.com/discourse/discourse-spoiler-alert), [discourse details](https://github.com/discourse/discourse-details) and some personal plugins (based on the creations of the community) : [some organized emojis](https://github.com/iunctis/vb_emoji), [a complete toolbar](https://github.com/iunctis/iunctis_toolbar), and some [bbcodes](https://github.com/iunctis/iunctis_bbcodes), but it doesn’t seem to be the problem considering the report. I didn’t add any plugins in the last 2 or 3 weeks.
Do you have an idea of the cause of that problem ? This error message is enough or do you need more info ?
Again, sorry for my english, I hope i’m pretty clear 😜

Almost certainly unsupported plugins. Unless we ship them, disable them and try again. Also you would need to look much further upstream in the logs for the actual error.

Hello again, thanks for the reply. Tonight, I edited the app.yml and delete my plugins, leaving only the Docker Manager plugin, it failed again during the rebuild app.
I copied the process :
- via [Docker Manager](http://www.iunctis.ovh/docker_manager.txt) (it always stops at this time)
- via [the rebuild app process](http://www.iunctis.ovh/rebuild_app.txt)
Nothing urgent here, my problem is not a priority, Discourse is up to date via Docker Manager and with a reboot it’s running fine. But if someone has an idea, I’ll take it 😉

We would need the full logs your error is deeper upstream

Where can I find the full logs ?
Is it the production log in /var/discourse/shared/standalone/log/rails ?

That’s what I did in this file : [http://www.iunctis.ovh/rebuild\_app.txt](http://www.iunctis.ovh/rebuild_app.txt)
Something’s missing ?

Do we need to kill that index?

Yes I added it because @sam asked me to. Maybe we should only index the first few characters of `value`?

aha … probably, we need to do something here.
I have a feeling that this is going to be tricky

I hope it’ll not be a big trouble.
Tonight, I upgraded discourse to the latest version and I cannot access any topic : [http://iunctis.fr/](http://iunctis.fr/)
```
Topic failed to load
Sorry, we couldn't load that topic, possibly due to a connection
problem. Please try again. If the problem persists, let us know.
```
I shutdown the server, restarted it, It doesn’t work
Could it be connected ? Or should I open a new topic ?

This should fix you up:
[https://github.com/discourse/discourse/commit/ea5ef3bcf69b70f9b68edd2aeb3b2122a61b2b45](https://github.com/discourse/discourse/commit/ea5ef3bcf69b70f9b68edd2aeb3b2122a61b2b45)
Wait till it hits tests-passed

It works ! Thanks @sam !
I tried to rebuild app first, it didn’t work. But a few minutes ago, the new version appeared in my docker manager and It worked
