xtrx: module verification failed: signature and/or required key missing - tainting kernel

[ducnguyenAstro]

Hi guys,

That was so excited to try out the XTRX. Having followed successfully the instructions until loading driver with the command: "modprobe xtrx"

Nothing shows up on /proc/modules. Checking out the dmesg there was an error: "xtrx: module verification failed: signature and/or required key missing - tainting kernel"

And there is no xtrx0 on /dev/ location and not with lspci either.

Thank you a lot for great help.

It seems you're using secure boot (UEFI) enabled kernel. That's why you get this message; however, this shouldn't affect you.

The device should appear in lspci regardless UEFI settings or driver presence.

What system are you using? Motherboard, CPU, slot where your XTRX is installed. This information will help to trigger the problem. You may send it xtrx@fairwaves.co

Thanks Sergey, (forgive me if i call it wrong)

XTRX is install on WMAX/WWAN pcie slot next to Wifi adapter on Thinkpad X230 running Ubuntu18.04.01.

Cheers,

AFAIK X230 has two miniPCIe slots and only one has PCIe lanes. Can you install XTRX instead of Wifi adapter and check?

Just tried it but computer suspended from booting up with " unauthorized card is plugged in" message.

Not sure how to bypass it. Probably waiting for USB3.0 adapter coming (has been waiting for 3 weeks). Thanks,

I see. It's a significant problem with some laptops called "white list" where BIOS doesn't allow unlisted VID/PID combinations.

None of our team have X230 so we can't help, but I suggest to reach specific forums like this to see if there's solution: https://www.bios-mods.com/forum/Thread-REQUEST-Lenovo-Thinkpad-X230-i-G2ETxxWW-Whitelist-Removal https://www.thinkwiki.org/wiki/Custom_BIOS https://forum.thinkpads.com/viewtopic.php?t=124541

I think USB3 is the safest option.

I close this bug since it's not related to the software. Feel free to reopen if you get it unlocked.
