About the wireless connection to upsuqared

Options

Hi everyone, I can't connect to the wifi by the dongle.
Here is the website I followed: https://www.linuxbabe.com/ubuntu/connect-to-wi-fi-from-terminal-on-ubuntu-18-04-19-04-with-wpa-supplicant
Here is the command on my board: wlxc... - is my dongle name, ourname - is the wifi name, password - is the password of ourname.

upsquared@ubuntu:~$ iwconfig
wlxc… IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry short limit:7 RTS thr=2347 B Fragment thr:off
Power Management:off

enp2s0 no wireless extensions.

lo no wireless extensions.

docker0 no wireless extensions.

enp3s0 no wireless extensions.

upsquared@ubuntu:~$ sudo iwlist wlxc… scan | grep ESSID
ESSID:"GMlab-01"
ESSID:"RSL_lab"
ESSID:"ourname"

upsquared@ubuntu:~$ wpa_passphrase ourname password | sudo tee /etc/wpa_suppli cant.conf

#psk=" password "
psk=0e3f4feffac29e9ec76530aefd9d06d963d35a4ea6fc93cc61565d5eeddd9cf9
}

upsquared@ubuntu:~$ sudo wpa_supplicant -c /etc/wpa_supplicant.conf -i wlxc…

wlxc…: CTRL-EVENT-SCAN-FAILED ret=-16 retry=1
wlxc…: CTRL-EVENT-SCAN-FAILED ret=-16 retry=1

It continued the last command repeatedly... I don't know what is the problem.

Thank you!
