efitools cant update vars: "Cannot write to db, wrong filesystem permissions"

[thiseyramo]

Hi,

I was using efitools 1.4.1 without problems, but since a few weeks I'm having troubles, when I try to update KEK key, efitools response:

Failed to update KEK: Operation not permitted

And if I try to update DB key:

Cannot write to db, wrong filesystem permissions"

I'm working on Ubuntu 18.04.

Making some tests, I clone and compile efitools from https://git.kernel.org/pub/scm/linux/kernel/git/jejb/efitools.git/ and with the latest version (1.9.4), everything works fine.

Somebody with the same problem?
