Ubuntu 16.04: Upgrade from 5.0 to 5.2

[Tha_Duck]

For some reason I am not able to upgrade from 5.0 tot 5.2 on Ubuntu 16.04. Normally it is quite easy. Maybe somebody can give me advice?

Ubuntu 16.04 with PHP 7.4.16 installed and running. Currently fine on Zabbix 5.0. When I add the new repositories and do a apt update & apt upgrade nothing happens. When I try to manually update zabbix-server-mysql, following notification is shown: zabbix-server-mysql is already the newest version (1:5.0.10-1+xenial).
For some reason I also have to use zabbix-frontend-deprecated. When I switch over to the normal version it will install the frontend with version 2.4....

Any clue as I am stuk :-(

Zabbix 5.2 server package for Ubuntu 16.04 is not published in the official Zabbix repository. Only agents are published. If you want to build Zabbix 5.2 server using Zabbix official package, please prepare a newer version of OS.

Clear, thanks.

I am wondering why Zabbix is telling me something different in the release notes of 5.2, but it makes sense as 16.04 will be EOL later this month.
