希望我來對地方了。
我正在遵循這個指示：https://tecadmin.net/install-zabbix-on-ubuntu/
zabbix-release_4.2-1+bionic_all.deb我沒有安裝該文件，而是下載了該zabbix-release_4.4-1+bionic_all.deb文件。
安裝zabbix-server-mysqlandzabbix-frontend-php和zabbix-agent，將顯示以下錯誤輸出：
ahmedsmaha@DarkStar:~$ sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-agent
