Symptoms
When Imunify360 is installed with hardened PHP, the system package manager, yum, cannot update RPMs and prevents cPanel updates.
Description
Imunify360 hardened PHP is not used on a CloudLinux server because CloudLinux already provides hardened PHP. If the Imunify360 hardened PHP repository is enabled, it must be disabled to prevent issues using yum.
Workaround
Disable Imunify360 Hardened PHP repo.
yum-config-manager --disable "imunify360-ea-php-hardened"
