Install zabbix on UCS 4.3-3 (Debian 9)

[MyKey0815]

Hello,

i want upgrade from Zabbix 3.4.2 to 4.0.3. My hostsystem is UCS 4.3-3 (based on Debian 9.6) => "... UCS 4.3-3 basiert auf dem im November veröffentlichten Debian Release 9.6..." (https://docs.software-univention.de/...ngelog:general)

Now I use the upgrade procedure https://www.zabbix.com/documentation.../debian_ubuntu and the part of "Debian 9"

Then I want to do the upgrade, but the message say:
"zabbix-frontend-php ist schon die neueste Version (1:3.0.7+dfsg-3).
zabbix-server-mysql ist schon die neueste Version (1:3.0.7+dfsg-3)."

If a show the version of zabbix server it show me 3.0.7:
root@ucs100092:~# zabbix_server --version
zabbix_server (Zabbix) 3.0.7
Revision 64609 21 December 2016, compilation time: Jun 4 2017 07:14:06

Can someone give me a hint, what is going wrong and what is the solution?

I found the solution for my problem:

mv /etc/apt/sources.list.d/zabbix.list.dpkg-dist /etc/apt/sources.list.d/zabbix.list

After this command i can install the 4.0.3 server on my UCS-System
