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 may help you find it.

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

What is your system locale set to?

Enter locale in terminal to check what the defaults are set to.
