Comment 7 for bug 1990891

It looks like in today's Kinetic update iwd was removed, perhaps because of this bug?

If so then the removal caused another problem: /etc/NetworkManager/conf.d/iwd.conf still existed after the iwd package was removed (I don't understand why, honestly), so even after I unmasked and re-enabled wpa_supplicant, NetworkManager still thought it was supposed to be using iwd instead. I had to delete iwd.conf by hand and restart NetworkManager to regain wifi connectivity.
