Error loading on Debian

[gerroon]

Hi

I am trying to install this driver on a remote machine. It seems like the driver isn't loaded after the installation/reboot using the install script so I try manual loading.

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

cat /etc/debian_version
12.8

uname -ra
Linux debian 6.1.0-28-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.119-1 (2024-11-22) x86_64 GNU/Linux

I didn't get any errors during the installation.

Hi @gerroon

I didn't get any errors during the installation.

There probably were not any errors.

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

So the system is running secure boot. There is not as much standardization among Linux distros as far as secure boot is concerned. At least not yet. This drivers installation as it currently is will handle secure boot on Ubuntu and the derivatives very well but beyond that it may take an investigation.

If you can look around the Debian web site for information about secure boot and how to do it, and send it to me, I'll see what we can do.

Thanks for the reply. I just checked dmesg and I see. It is a remote PC so not sure how much I can deal with the secure boot thing, but thanks for the info.

It is possible to key the driver so that it works. It just depends on the distro that is being used. FYI: By the time Debian 13 comes out, this won't be an issue as the adapter will be plug and play.

Another thought: Here is the Main Menu for this site:

https://github.com/morrownr/USB-WiFi

If you read menu items 1 and 2, you will see that there are many plug and play adapters available for Linux. You can go as high as WiFi 6e adapter with the kernel and Debian 12 that you are using. No more hunting for and compiling drivers.

[gerroon]

Thanks for the useful information. Most of these cards aren't available in the host country's Amazon stores. I will keep looking at them, to see if I can find the same chipsets in other brands. I am guessing the chipset is what matters.

Do you think that upgrading to "testing" would resolve the issue for me? If not I am guessing that I can't make a signed compiled driver myself.

@gerroon

It is. for the most part, the chipset that matters. You can see the Plug and Play List and there is Chipset menu item on the Main Menu as well.

Here is message showing another adapter that I am considering adding to the Plug and Play List. Maybe it is available to you. Be careful about model numbers as TP-Link has many model numbers that are nearly the same.
