Hello everyone,

I'm trying to install Openproject on a fresh installation of Ubuntu server 18.04. I installed everything, but when I run this command I get the following result:

sudo openproject configure

*   OpenProject requires UTF-8 encoding set on MySQL < 5.7              * 
        and UTF-8mb4 beyond that. Please ensure having set 
    *                                                                       * 
            production: 
    *         encoding: utf8mb4                                         *

*   in config/database.yml.                                             * 
        Otherwise, you WILL run into encoding issue when using 4 byte 
    *   UTF-8 characters since utf8 encoding in MySQL doesn't support them. *

*   If you have been running utf8 in the past, please see this guide    * 
        on how to convert your database:
