Upgrade - frontend problem

[rlukaszczyk]

Hi,
Debian 9, after upgrade zabbix 4.4 now I get:

The frontend does not match Zabbix database. Current database version (mandatory/optional): 4050136/4050136. Required mandatory version: 4050027. - . Zabbix 5.0.0rc1 (revision ffde654900)

Are you sure you upgraded to 4.4.x? That looks more like you accidentally upgraded to a pre-release version of Zabbix 5.x.

Did you upgrade using packages? What zabbix-related packages are currently installed on your server?

Upgraded from:

deb http://repo.zabbix.com/zabbix/4.5/debian stretch main
deb-src http://repo.zabbix.com/zabbix/4.5/debian stretch main

And here is a problem.it's prerelase. Installed packages:


zabbix-agent/unknown,now 1:5.0.0~rc1-1+stretch amd64 [installed]
zabbix-apache-conf/unknown,now 1:5.0.0~alpha1-1+stretch all [installed]
zabbix-frontend-php/unknown,now 1:5.0.0~alpha1-1+stretch all [installed]
zabbix-release/unknown,now 1:4.5-1+stretch all [installed]
zabbix-server-mysql/unknown,now 1:5.0.0~rc1-1+stretch amd64 [installed]

The repository you are using is not for 4.4. Since it is 4.5, it is a development version before the release of 5.0.
It seems that you have already upgraded to the development version of 5.0. Do you have a backup of the previous database?
If you have a previous backup, please upgrade to version 4.4 using the repository.

https://www.zabbix.com/download?zabbix=4.4&os_distribution=debian&os_version=9_stretch&db=mysql&ws=apache

# wget https://repo.zabbix.com/zabbix/4.4/debian/pool/main/z/zabbix-release/zabbix-release_4.4-1+stretch_all.deb
# dpkg -i zabbix-release_4.4-1+stretch_all.deb
# apt update

If you don't have a previous backup, you'll have to upgrade to 5.0. However, please be aware that if you are using Debian 9, you will need an environment of PHP 7.2 or later, so you cannot build the environment with only the OS standard packages.

I understand now and I have backup. Thanks for help!
