PackageKit error: PackageKit::Transaction::ErrorInternalError “Internal error” “Error running transaction: package VirtualBox-6.1-6.1.34_150636_fedora36-2.x86_64 is already installed”

but i dont see it in start menu or not installed - Discover , any ideals?

VirtualBox is proprietary from oracle even though free to use.

The KVM virtual machine manager does not manage it, but instead is designed to work with libvirt and QEMU as an all free and open source VM environment that is available on fedora. As your image shows it is designed to manage VMs under KVM, Xen, or LXC using the libvirt tools.
