Install Qubes and it will give you an easy option to install Whonix. Out of the box Qubes supports Debian, Fedora, and Whonix very well. If the Qubes installer works on your hardware, the setup is a breeze. Qubes does have a bit of a learning curve, but largely non-technical (separating activities out into different VMs, and installing software onto a template instead of directly in the VM)
