Unable to configure wifi interface on raspberry pi 3 B+

No its annoying to have to plugin like that. Still, done once and now you’re up and running .

Hi

I have followed Juans guide to the letter, but my Pi stil dont connect to the wifi nor wired. Enclosed pictures about my error on the tv.

Here my system-connections file withour extensions:
[connection]
id=hassos-network
uuid=27c2ab96-4bb7-4a43-9ec5-c975dbb0b0f1
type=802-11-wireless

[802-11-wireless]
mode=infrastructure
ssid=MY_SSID

Uncomment below if your SSID is not broadcasted

#hidden=true

[802-11-wireless-security]
auth-alg=open
key-mgmt=wpa-psk
psk=MY_PWD

[ipv6]
