[Bug 2129164] Re: nullboot 0.5.3-0ubuntu-0.24.04.1 does not install

[Julian Andres Klode]

nullboot only supports azure-fde kernels on Azure Confidential VMs (and
similar kernels in theory, none exist to my knowledge); it does not work
without /usr/lib/linux/efi being present.

** Changed in: nullboot (Ubuntu)
       Status: New => Won't Fix

Title:
  nullboot 0.5.3-0ubuntu-0.24.04.1 does not install

Status in nullboot package in Ubuntu:
  Won't Fix

Bug description:
  When updating to the nullboot in noble-updates, I get the following
  error:

  Setting up nullboot (0.5.3-0ubuntu0.24.04.1) ...
  2025/10/21 09:21:39 cannot add new assets from /usr/lib/linux/efi : open /usr/lib/linux/efi: no such file or directory
  dpkg: error processing package nullboot (--configure):
   installed nullboot package post-installation script subprocess returned error exit status 1
  Errors were encountered while processing:
   nullboot

  The previously installed version of nullboot was 0.5.0-0ubuntu3.

  When using apt-file to search for packages that contain
  /usr/lib/linux/efi I can only find kernels suffixed with -azure-fde.
  I am not in an azure environment and I am using -generic kernels.

  This appears to have been already reported in

  was not investigated or resolved.
