Mac-address random spoofing before web connection

I installed Qubes OS 4.0.4 on my laptop. And I need to randomize mac-address which is visible for external WiFi routers.

This should be done before first internet connection with Qubes.

I read in manual that I have to edit template (“write the settings to a new file in the /etc/NetworkManager/conf.d/ directory inside of template”).

I see fedora-32 template. But it’is impossible to open any directory inside of this Fedora-32 (no “fedora 32: files”, only “fedora 32:terminal”). And it’s impossible to use sudo nano in fedora 32 terminal (“command not found”).

What sould I do in this case?

now, try do like this
open fedora 32:terminal
then cd /etc/NetworkManager/conf.d/ && ls ; echo "dnf check" && sudo dnf
what is the output

Thanks. Empty file was created. But how to edit and save without nano? Vi shows read only and permissions troubles.

try sudo dnf install nano to install nano
if that doesn’t work then you need help from other people since i don’t know how to use vi
