my computer does not appear available wifi network connection. To solve this, I try install the driver rtl8723be, but not worked!

I saw the following post. He suggest execute the following command:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info

that generate the file 'wireless-info.txt' follows such file:

When I execute

sudo modprobe rtl8723be && sudo dmesg | grep 8723 appears:

 modprobe: ERROR: could not insert 'rtl8723be': Required key not 
 available

Please how can I resolve this?

Is it necessary Disable Secure Boot to work? – Frank May 20 '23 at 22:34
Yes when you aren't using the kernel module, it must be something you downloaded and compiled – Jeremy31 May 20 '23 at 22:37
