Sometimes yum/apt on your OS breaks due to some conflict or abrupt termination of yum/apt command. When this happens Webuzo does not allow you to install new packages like PHP, Apache, etc to prevent further breaking since installation of these packages require yum/apt to be working.
In such cases you need to use the following command and follow the steps on screen to fix yum/apt
RedHat - CentOS/AlmaLinux
yum clean all
Debian - Ubuntu
dpkg --configure -a
This should resolve your issue and the apps installation should work fine now.
