I SSH to the Pi and login with User pi and PW max2play.
When I issue the „su“ command and enter PW max2play again I get: „su: Authentication failure“.
Any idea? I have a PI 4 and am running the m2p_buster_rpi-v250.img.zip
Thanks for any help!
P.S. I need root privileges because I wish to edit /etc/wpa_supplicant/wpa_supplicant.conf in order to troubleshoot the PI not connectin to Wifi with hidden SSID.
