sbsigntool prints scary warning about invalid PE-COFF files which should be debug infos (file-aligned section .text extends beyond end of file; checksum areas are greater than image size. Invalid section table?)

i get the same problem when i use uck to modify a livecd. My computer is 13.04 and it occurs when i run "apt-get dist-upgrade" to update linux-signed-image-3.8.0-19-generic

Status changed to 'Confirmed' because the bug affects multiple users.

Still happens, probably more scary than severe.

I'm running 13.10, and a recent dist-upgrade resulted in:

Same for 12.04.3 LTS. During dist-upgrade:

I'm running 13.10, and a recent "apt-get install linux-headers-generic build-essential dkms" gives:

I asked around and this is an overly verbose sbsigntool which should probably not a warning but a debug message:

I have 2 PC's running the same OS (64 bit 16.04.1) and mobo and kernel. Only one gives the warning message.

Setting up linux-signed-image-4.4.0-57-generic (4.4.0-57.78) ...

Still not fixed.

Is it possible that this bug can affect motherboard efi boot/bios ?
Because when I use windows in my ASUS H97 plus all works fine.

But when I switch to ubuntu, often after an upgrade (signed image) the computer locks itself not booting at all during BIOS UEFI BOOT !!Than I have to remove bios battery and reset bios using jumper (and also pressing boot button for 10 seconds) than after that I regain PC control.

The very first time I had to remove all peripherals from motherboard... This happens only with ubuntu and only after an upgrade... If use ubuntu or Windows normally (no upgrading) I can go on for months without any problems.. BUT if I upgrade ubuntu this not always, but often happens....

I forget to mention that tis bug affects me also...

No. This is a spurious warning message in a signing utility, it does not
impact the runtime behavior of EFI boot on Ubuntu.

Affected. Ubuntu 14.04:

Setting up linux-signed-image-3.13.0-129-generic (3.13.0-129.178) ...
warning: file-aligned section .text extends beyond end of file

version 17.10

Ubuntu 16.04 affected.

Same 2 lines warnings by here after apt upgrade when setting linux-signed-image-4.4.0-96-generic (4.4.0-96.119)...

Linux box 4.4.0-93-generic #116-Ubuntu SMP Fri Aug 11 21:17:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Also Ubuntu Mate 17.10

I have reported a bug report for a similar error. The only thing missing is, no mention about sbsigntool.
