root@forum:/var/discourse# ./launcher rebuild app
Ensuring launcher is up to date
Fetching origin
Launcher is up-to-date
Stopping old container
- /usr/bin/docker stop -t 10 app
I’m not using spaces instead of tabs.
I went to cd var/discourse/ and edited my app.yml

You need to include more information about what is wrong. Are there any error messages when you run rebuild?

Also, [make sure your app.yml has no white space errors.](http://www.yamllint.com/)

I got disk space error and ran .launcher cleanup but didn’t do anything. Don’t see any other errors or anything in logs

Do you have any disk space? What does
```
df -h
```
say?

I’m not a pro, but until someone helps you I would try this :
First a docker upgrade and a reboot :
```
sudo apt-get upgrade docker-engine
shutdown -r now
```
Reconnect after a few seconds. And try a rebuild again :
```
git pull
./launcher rebuild app
```
