I seem to be unable to use Docker Manager to upgrade my installation. It fails because it can’t find the gem 6to5-source, which according to [RubyGems.org](http://RubyGems.org) has been yanked.
This is the log:
```
$ cd /var/www/discourse && git fetch && git reset --hard HEAD@{upstream}
HEAD is now at a26853c try to work around caching bug in spec
********************************************************
***Please be patient, next steps might take a while***
********************************************************
$ bundle install --deployment --without test --without development
Fetching source index from https://rubygems.org/
Could not find 6to5-source-3.3.7 in any of the sources
```
Also, the manager does not seem to handle this well - my site is unavailable now. It probably should check that all gems are available before bundling, but that’s a different issue.
I managed to download the correct version of the gem from [RubyGems.org](http://RubyGems.org) manually, but is there a way to install it so the manager can upgrade?
Thanks in advance
**edit** : I figured maybe restarting the containers and reloading the upgrader would help, but that was a bad idea. Now the manager tells me everything’s up to date, which it most definitely isn’t.
**edit** : Can’t reach it at all now, this is the output of ./launcher logs:
```
ok: run: redis: (pid 30) 78s
ok: run: postgres: (pid 33) 78s
supervisor pid: 567 unicorn pid: 572
Could not find 6to5-source-3.3.7 in any of the sources
Run `bundle install` to install missing gems.
config/unicorn_launcher: line 44: kill: (572) - No such process
config/unicorn_launcher: line 10: kill: (572) - No such process
exiting
```

I’ll look into this ASAP.
I know the 6 to 5 project was renamed to babel but it would be really bad if they just yanked the old gem when projects depend on it.

Okay I’ve just pushed this to master:
[https://github.com/discourse/discourse/commit/4691fe35b3ac4e05d8b842903151c1ebfee08149](https://github.com/discourse/discourse/commit/4691fe35b3ac4e05d8b842903151c1ebfee08149)
You should be able to `./launcher rebuild` now.

Will this need to be backported onto beta and stable?

```
Bundle complete! 92 Gemfile dependencies, 189 gems now installed.
```
Thank you so much, also for being so fast! I would assume that beta and stable deployment is still broken though? Not as horrible for me, as my site’s running on master, but I get that that’s not the recommended way 😉
Anyway, that’s a crappy move to just yank the old gem, and break deployment processes that depend on it.

Yes good call, I will backport it to beta/stable now.
edit: The fix is now in beta and stable branches too.
