When creating an AppVM or StandaloneVM from Fedora-29-minimal and setting the netvm to sys-whonix I cannot access the general web nor use the update-proxy to update the machine. The Fedora-29-minimal TemplateVM can use the update-proxy just fine.
This should use only Qubes repos, but I still get thrown this error:
sudo dnf install qubes-usb-proxy
Error: Error downloading packages:
