My Ubuntu Server 22.04 has a Zabbix Server 6.4. I ran the apt update command followed by the apt upgrade command. But a problem occurred when the update finished: my Zabbix server stopped working and won’t start anymore. Checking the update log, I noticed that Zabbix was upgraded from 6.4.12 to 6.4.15. I didn’t expect the packages to skip several versions like that. Does anyone have any ideas on how to get the server running again or know if there are any commands missing to complete this update?

I only checked the log files; I don’t have enough knowledge to apply solutions.
