Failed to start Zabbix Server - where's my /usr/sbin/zabbix_server?

[whisky17]

Hi,
I can't get my zabbix Server running, even after upgrading from 5.2 to 5.4 it doesn't start.

/usr/sbin/zabbix_agent2 /usr/sbin/zerofree /usr/sbin/zic

It seems that the reference to /usr/sbin/ is not correct. But which is my right path? I'm using ubuntu 20.04
Any idea? My /var/log/zabbix/zabbix_server.log is absolutely empty.
Thanks!

In case it helps, I'll share my way of working with Zabbix when upgrading the underlaying Debian version (which I believe goes pretty much the same in Ubuntu).

- First I upgrade Zabbix to the latest supported version on the current Debian version, and verify that everything works, database is fine, no errors in the logs, etc.
- Before the Debian upgrade I remove (apt uninstall) the currently installed Zabbix packages, just to be sure there won't be any conflict with the previous Zabbix binaries and the new OS libraries and such. Note that this does not remove the configuration files, so they will still be there waiting for further actions. (Backups required in any case when upgrading, right?)
- I upgrade Debian, using the officially documented process.
- After the successful Debian upgrade I install the same Zabbix version that I previously used (but using the zabbix-release package for the new Debian version, of course), and verify that everything works correctly, without errors in the logs, etc.
- Then I can do any additional Zabbix upgrade if needed.

Thanks, Markku.

I restore my Zabbix VM from daily backup.

Then I upgraded (first) Zabbix, (then) MySql and and everything looks fine.
There was an issue with upgrading MySql from 5.7. to 8.0. I upgraded it from http://repo.mysql.com/ with

apt-get ----allow-insecure-repositories

.

After that I upgraded Ubuntu from 18.04 to 20.04. Now, I have this issue:

No ideas, what to do next...

Uninstall all zabbix packages, and then install Zabbix server again with the usual instructions from https://www.zabbix.com/download
