Comment 12 for bug 1921539

I did the following test, the result is failed.

Machine: Dell Latitude 5300
BIOS: 1.10.4
Test case: download 1.10.4 bios cab from lfvs, and reinstall the bios using fwupd with the command "fwupdmgr install xxxx.cab --allow-reinstall"

Pass means: we can run BIOS re-install.
Failed means: we can't run BIOS re-install and we will see the error message on the screen. The error message is shown on the monitor in text with blue background.

shim and shim-signed 15.4-0-ubuntu1 + fwupd and fwupd-signed 1.4.5-1
        secure boot off: Pass

shim and shim-singed 15.4-0-ubuntu1 + fwupd and fwupd-signed 1.4.5-1
        secure boot on, failed msg: Verification failed: (0x1A) Security Violation

shim and shim-signed 15.4-0-ubuntu1 + fwupd and fwupd-signed 1.4.7-0~20.10.1
        secure boot on, failed msg: Verification failed: (0x1A) Security Violation

        The following pkg were install to do above test.
        fwupd_1.4.7-0~20.10.1_amd64.deb
        fwupd-signed_1.30.1+1.4.7-0~20.10.1_amd64.deb
        libfwupd2_1.4.7-0~20.10.1_amd64.deb
        libfwupdplugin1_1.4.7-0~20.10.1_amd64.deb

Is the test procedure wrong or need to install something else?
