qvm-usb fails if sys-usb template is set to fedora-24-minimal

[Grzesiek Chodzicki]

qubes-usb-proxy not installed in VM is thrown in dom0 terminal after running qvm-usb -a if sys-usb uses minimal fedora 24 template. Necessary packages were installed in fedora-24-minimal beforehand

Steps to reproduce:
1. Launch fedora-24-minimal terminal
2. sudo dnf install qubes-usb-proxy qubes-input-proxy-sender (or switch to root beforehand if sudo not installed)
3. Shutdown fedora-24-minimal
4. Shutdown sys-usb
5. Change sys-usb template to fedora-24-minimal (qvm-prefs -s sys-usb template fedora-24-minimal)
6. Launch sys-usb
7. Try attaching any USB device via qvm-usb

Observed behavior:
ERROR: qubes-usb-proxy not installed in VM

Expected behavior:
Device is attached to an AppVM

Additional details:
Switching the template back to regular fedora-24 causes the qvm-usb to work fine.

Are you sure that the necessary packages and all dependencies are

This does seem to be the issue, however manually installing the pycairo package does not resolve the problem. Fedora-24-minimal has the qubes-usb-proxy-1.0.5-1.fc24.noarch package installed however Dom0 still throws the usb-proxy not installed error.
