We tried to install discourse on Ubuntu 16.04 and everything went smoothly until we got this error. Anyone can figure out what is wrong and how to fix it?

What is your system locale set to?
Enter `locale` in terminal to check what the defaults are set to.

Run the following command:
`sudo dpkg-reconfigure locales`
then select and enable `en_US.UTF-8 UTF-8` and default it to `en_US.UTF-8` on the next page.
after that, Run ./discourse-setup once again. this should be fixed.

Your `app.yml` has invalid data. Please fix it.

What is app.yml? We used docker to download the latest release of Discouse and the server setup is totally new and fresh? We didnt do any modifications other than the local reconfig as suggested by Bhanu.

SSH into the machine and then:
```
cd /var/discourse
nano containers/app.yml
```
That’s where all your config lives. You have a bad character there somewhere. Pasting the contents into [http://www.yamllint.com](http://www.yamllint.com) may help you find it.

I solved it - the installation had added an ^ to the admin email.
