To avoid confusion, I shall use the original example provided by Debian Wiki (https://wiki.debian.org/WiFi/HowToUse) which is: su -l -c "wpa_passphrase myssid my_very_secret_passphrase > /etc/wpa_supplicant/wpa_supplicant.conf" In a terminal, I typed: username@hostname:~$ su -l -c "wpa_passphrase JupiterRising 1234567890 > /etc/wpa_supplicant/wpa_supplicant.conf" Password: su: Authentication failure The output is Authentication failure Best regards.
