This is not about running in insecure mode, it's about the fact that you
are on an EFI system but the /sys/firmware/efi mount point that the
kernel uses to expose EFI nvram variables to the system is unusable.
We have had a number of reports of such problems but have yet to isolate
a cause.
Opening a bug task on the kernel, since this may be a kernel filesystem
bug.

Bug description:
The installer crashed at the very end with a warning that my computer
might fail to boot.
It booted alright but after logging in I get a pop-up to signal that
shim-signed has failed to install.
Something to do with my system (EFI) running in insecure mode?
