Steps to reproduce:

1. Click "Create Zabbix server Droplet" button on the marketplace (https://marketplace.digitalocean.com/apps/zabbix-server)
2. Fill the form by selection region, root user password, etc.
3. Choose "Basic" DigitalOcean plan (5$/month)
4. Check your droplet when it is ready

Result:
Zabbix doesn't work because Zabbix database is empty. From Zabbix server log file:

  5339:20211203:212343.039 using configuration file: /etc/zabbix/zabbix_server.conf
  5339:20211203:212343.047 cannot use database "zabbix": its "users" table is empty (is this the Zabbix proxy database?)

Frontend error:

Database error
Unable to determine current Zabbix database version: the table "dbversion" was not found.

Expected:
Zabbix is up and running
