Ultramarine Linux: error updating secureboot dbx

Support Linux Support

hello everyone.

I get this error message during an automatic upgrade attempt of “Secure Boot dbx” by gnome-software. It is repeatable.

failed to write data to efivarfs: Error writing to file descriptor: Invalid argument

My chrultrabook is a Lenovo IdeaPad Flex 5i Chromebook, it’s a TigerLake, board name LILLIPUP.

I’m not linux-savvy, I just know how to read instructions. I’ve set up my system quite satisfactorily.

Ultramarine is awesome to me, it solved problems I had while running Debian (notably, it wasn’t able to update the kernel automatically).

this is the only problem I’m encountering with it (I didn’t get the problem for the ten months I was running Debian 12). Is it a firmware thing? Is it maybe because it doesn’t recognize the flashed MrChromebox firmware?

Thanks!

Did you ever figure this out? I’m having the same problem with a Lenovo 500e 2nd gen on Fedora KDE.

No I didn’t. Nobody answered me here.

But on the Ultramarine Discord, Weird tree Thing explained that “the uefi implementation does not support updates through efi variables”.

So either you ignore this shit as i’ve learned to do (and it’s annoying) or hope that a future mrchromebox release includes updated secureboot info. Which hasn’t happened yet.
