Try this:
The file /var/run/wpa_supplicant/wlan0 is a socket that the process creates to communicate with the interface. This error is usually thrown when a stale socket file exists from a previous instance that didn't clean up properly. In some cases, wpa_supplicant explicitly recommends doing this:
ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
You can then execute wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -D nl80211 as before.
Code:
sudo rm -f /var/run/wpa_supplicant/wlan0ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
You can then execute wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -D nl80211 as before.
