The frontend does not match Zabbix database

[hartkl]

Just did a fresh install of Zabbix 6.4 on Ubuntu 20.04. Install went fine but when I log in to the web UI for the initial setup on the Configure DB connection I am getting the error "The frontend does not match Zabbix database. Current database version (mandatory/optional): 6040000/6040026. Required mandatory version: 4000000." Any idea why I would get this on a fresh install and how do I fix this?

Found my issue, when installing the package for Ubuntu 22.04 the Zabbix package installed the 4.0 front end, had to build a Ubuntu 20.04 and 6.4 installed perfectly.
