Environment

• AlmaLinux 8
• cPanel
• Imunify360

Solution

It appeared that ImunifyAV was previously installed and its leftovers had been found. The installation issue was fixed by uninstalling ImunifyAV according to the general procedure and then by running a clean Imunify360:

wget https://repo.imunify360.cloudlinux.com/defence360/imav-deploy.sh

bash imav-deploy.sh --uninstall

wget https://repo.imunify360.cloudlinux.com/defence360/i360deploy.sh i360deploy.sh

bash i360deploy.sh --key ***

Cause

The leftovers of the previously installed ImunifyAV product caused conflict during the Imunify360 installation.
