Delete '/run/wpa_supplicant/wlan0' manually if it is not used anymore
Failed to initialize control interface '/run/wpa_supplicant'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

 > wpa_supplicant did not start, possible configuration error
