Re: Keyboard stopped working

[Arbol One <arbolone@hotmail.ca>]

As stated in the OP, with the USB containing the installation files for Debian 12 already inserted in the computer, I booted up the computer and instead of going to the installation files, as it should, I get a message saying  

Verifying shim SBAT data failure: Security Policy Violation. 

Som6has gone seriously wrong: SBAT self-check failed: Security Policy Violation. 

There's something in me saying that it is a virus, but that might be 'cos I'm still traumatized by all those years of Win-OS usage. 

Again, any help would be greatly appreciated.

Thanks in advance.

By the way, I've tried other keyboards but to no avail.

In my Debian 12, the keyboard stopped working all of the sudden, i tried using the 'Screen Keyboard', but it didn't work either. Coming from the world of Windows 10, I intended to reinstall the Debian. 

With the memory stick containing the Debian installation files plugged, I proceeded to reboot the computer. 

The booting process then tells me something I've never seen before, something along the lines of 

'Something went terribly wrong. Security Policy Violation, ... , SBAT self check failed, ... '

Please post the full error message. Have you tried disabling secure boot?

 

What's going on with Debian 12, I'm not allowed to reinstall Debian?

Do I need to install Windows 11, and then reinstall Debian?

If anyone can suggest a better solution

it would be greatly appreciated. 

Thanks in advance.

PD : 

After the 'Screen Blackout' kicked in and then moving the mouse, I was asked to enter the password, and the keyboard worked!

However, the keyboard doesn't work on any other application; no matter what key I press.
