Ubuntu 23.10 Secure Boot?

[Amondale]

sudo modprobe 88x2bu
modprobe: ERROR: could not insert '88x2bu': Key was rejected by service

This is after compiling per the instructions in Manual Installation (sudo make sign-install) with no errors reported and successful shim install via mokutil.
TIA,

Hi @Amondale

This driver working fine with Secure Boot with Ubuntu 23.10 here. Installation via "sudo sh install-driver.sh" tested.

Did the system bios have secure boot turned on when you installed Ubuntu?

Not certain, but probably did have secure boot turned on. I am wondering if there is a way to rip out all trace of this driver, hoping that this usb adapter is supported natively, like Ubuntu 22.04.3 (modprobe finds 88x2bu) after insertion with no driver loaded from this github site.

If it is not turned on when installing the os, things won't go well for things like installing this driver. Well, it will install but it won't work.

I am wondering if there is a way to rip out all trace of this driver,

$ sudo sh remove-driver.sh

The in-kernel driver and this driver are not feature equal. They both have features the other does not so you just have to see which works better for you. I recommend using at least kernel 6.4 for the in-kernel driver.

To test, simple go into the bios and turn secure boot off and reboot. If the driver works, then you know if it is a secure boot setup problem.
