I tried to perform "sudo dnf install linux-firmware" as recommended by the user's FAQ and get "Error: Failed to synchronize cache for repo 'updates'"
(by the way, the faq still has yum instead of dnf)
I'm currently trying to find an offline workaround or solution. I would appreciate assistance in that endeavor, or alternately, a heads up that I need to find another tree to bark up.
When I first instaled qubes, I remember using network manager, after that, the applet always appeared on the taskbar.
