Pacman -Sy archlinux-keyring

during the installation of arch in qubes os 4.3.1 (StandaloneVM with sys-firewall → sys-net) I don’t have any internet connection and when I type ‘pacman -Sy archlinux-keyring’ nothing happens. Why I do not have any internet connection?
Before that I do this with the right parameters taken from arch settings in Qube Manager:
ip link set enX0 up
ip addr add [ip] dev enX0
ip route add [gateway] dev enX0
ip route add default via [gateway]
echo “nameserver 10.139.1.1” > /etc/resolv.conf
Do I need the same kernel in arch>sys-firewall>sys-net?
sys-firewall and sys-net are been tested by firefox in personal so there is internet there, please help, thank you!
