Error when trying to start discourse could not find expected while scanning a simple key

Below is the error I am getting. I’ve manually installed lighttpd, which removed that error and manually installed rails but I still get this. I haven’t found much out there so i hope i’m not overlooking something simple. Thanks:

Same problem… why publish a One-Click install that hasn’t been tested properly and doesn’t work?!?

    See the link from @xinbenlv above. It is for Ubuntu 18.04.

      I followed your link to the 30 minute install and that works fine on 18.04

        Solved!

        Hopefully this will help anyone else who has this same issue. If you actually use a strong password it breaks the installation script. The One-Click droplet works fine as long as you avoid special characters in your password.

        The One-Click droplet also cannot be installed using https by default in the same way the 30 min install link can. Pretty sure it can be added later, I’m just not there yet.

What process did you use to install Discourse?

I used the 1 click droplet setup on the $10 plan. After the droplet was created I logged in to root via SSH, entered email, domain and sftp info. Then I received the following:
