Hi,
Thanks a lot, I've updated /etc/qubes-rpc/policy/qubes.UpdatesProxy and will test next time an update is available.
I've issued "qubes-prefs updatevm" on dom0 terminal and the answer was "sys-firewall-wifi", which is my firewall VM and not sys-net or sys-net-firewall. Should it work over the wifi? I do not remember having updated qubes-prefs updatevm when I created sys-net-wifi/sys-firewall-wifi.
Regards
