default debian-template

[telepath]

Since Qubes 4.1 it's possible to use debian as default template for all qubes. The script assumes a fedora default template and fails if the management qube is created with a debian template.

I see two ways to solve this: a) make having a fedora template a requisit and extend the script to find a suitable template (latest installed fedora template) b) make the script compatible with debian as well as fedora, so it does not matter which template is default

Workaround: For now, installing a fedora template and setting it as default for the first run of the script works fine.
