(Premise: I'm experienced Linux and Zabbix sysadmin)

I think the official Zabbix package 7.0.26 LTS has an incorrect systemd unit for Zabbix Proxy.

So, this package seems problematic:

https://repo.zabbix.com/zabbix/7.0/ubuntu/pool/main/z/zabbix/zabbix-proxy-sqlite3_7.0.26-2%2Bubuntu24.04_amd64.deb

Steps to reproduce:

1. Ubuntu Server 24.04 LTS (noble) (normal, not minimal)
2. Install Zabbix 7.0 LTS package https://www.zabbix.com/download?zabbix=7.0&os_distribution=ubuntu&os_vers%20ion=24.04&components=proxy&db=sqlite3&ws=
3. sudo apt install zabbix-proxy-sqlite3 zabbix-sql-scripts
4. sudo systemctl start zabbix-proxy

Result:
systemd[1]: zabbix-agent.service: Can't open PID file /run/zabbix/zabbix_agentd.pid (yet?) after start: No such file or directory
systemd[1]: zabbix-proxy.service: Failed with result 'protocol'.
**

Expected:

The systemd service works.

Workaround:

Replace the zabbix-proxy.service with the exact content of this forum thread:

So, the systemd unit becomes this one:
