Error when trying to install Manjaro

==> Running post hooks
  -> Running post hook: [sbctl]
Secureboot key directory doesn't exist, not signing!

This is just an information and can me ignored.

If you want to get rid of the message, run

sudo sbctl create-keys

This does not in any way enable or configure secure boot - it is just generating a key to be used - should you later decide to implement secure boot.

[INFO] What is it with Secure Boot, why is it not supported OOB?

It is not relevant when your GPU is an integrated Intel GPU as your inxi shows

@Elektroniko

Graphics:
  Device-1: Intel Xeon E3-1200 v2/3rd Gen Core processor Graphics

I have no idea as to why the message appear but since it appears just
after the Running build hook: [kms] message it could be related to the hook.

Manjaro Linux default to use kms and it is thus possible that your system is not happy about it.

Edit /etc/mkinitcpio.conf, scroll down to the HOOKS= and remove kms - then rebuild init using

sudo mkinitcpio -P
