[pawelp]

Instalation on Ubuntu 14.04 LTS (32bit) - with zabbix help. Everything was ok - 2 days. Now frontend is ok, but zabbix-server dont start (info on website and logs) Ubuntu was update with apt. Now i have info in logs:

The server does not match Zabbix database.

I export database and tray run it for test on debian8. Installation from help - everything good. On Debian i have version: 3.0-1+jessie (aptitude)
but when i start zabbix-server:

2567:20160217:203029.458 Starting Zabbix Server. Zabbix 2.2.7 (revision 50148).

Can be determined from this message, it seems 2.2.7 has been started.

How did you perform the upgrade, please tell me the detailed procedure.

[pawelp]

It was clean installation Zabbix 3.0 on clean server, and because i have problem with connection snmp with dns i apt-update them and configure samba, winbd etc.
Beacuse zabbix is my best friend, and zabbix 3.0 is the best and pretty (like a girlfriend ;-) - I backup my templates, databse, and start one more time.

I make all the same things like first time, installation after get deb package, configure. So i write something, when the problem repeat.

According to log you posted you are running Zabbix server version 2.2.7 while database version is 3.0.

[pawelp]

I know, but why is 2.27? auto update after apt-get upgrade to lower version? its possible?

dpkg -l|grep zabbix

dpkg -S $(which zabbix_server)
