I’m able to see that the appropriate wireless interface is now available:
# ip l
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq qlen 1000

link/ether b8:13:32:4a:0e:86 brd ff:ff:ff:ff:ff:ff
The problem is that whenever I try to set that wlan0 interface up or use wpa_supplicat it fails to do so and I get the following prompt:
