Attempting to build a p2v iso to convert machines to vms.
When you run virt-p2v-make-disk -o ./p2v.iso it eventually throws an error:

```

an error

If reporting bugs, run virt-builder with debugging enabled and include the
complete output:

virt-builder -v -x [...]
```

Manually changing the script to use 'apt-get update -y' instead of 'dnf update -y' allows the script to work.
