    Lubuntu 18.04 64 bit: wifi adapter rtl88x2BU driver problem

    Hi,
    I have lubuntu 18.04 64 bit with a wifi adapter rtl88x2BU. The adapter worked well up to yesterday with this driver (patched version) when I was using the linux kernel v5.0.x. After an update to the version v5.3.x I cannot compile the driver anymore. So after some searches on the Web I found that this driver should work. However, it does not work and I have an error on boot.
    Code:
    Failed to start Load Kernel Modules
    See 'systemctl status systemd-modules-load.service' for details
    The module 88x2bu.so is the one related to the rtl88x2BU.

    Any idea?
    Thank you

    Code:
    dmesg | grep 88x2bu
    [   13.027381] 88x2bu: loading out-of-tree module taints kernel.
    [   13.028498] 88x2bu: module verification failed: signature and/or required key missing - tainting kernel

    Now the wifi adapter is working even if the led does not blink. I do not know the reason.
