Could not apply database update "DBXUpdate-2016-08-09-13-16-00.bin": Invalid argument

[cmurf]

I'm experiencing this bug on two computers:
[ 0.000000] DMI: /NUC5PPYB, BIOS PYBSWCEL.86A.0074.2018.0709.1332 07/09/2018
[ 0.000000] DMI: HP HP Spectre Notebook/81A0, BIOS F.41 06/15/2018

Both run Fedora 29, and have dbxtool-8-7.fc29.x86_64, and kernel 4.19.2-300.fc29.x86_64.

From the NUC journal (same as on the HP):

And then run

Thanks for your interest in dbxtool. dbxtool has been obsoleted by fwupd; we recommend using that instead and will shortly be archiving this repository.
