[Bug 1297069] Re: During the installation under UEFI mode, "Could not open \EFI\BOOT\fallback.efi: 14" shows after passed the BIOS phase.

[Launchpad Bug Tracker]

This bug was fixed in the package shim - 0.7-0ubuntu4

---------------
shim (0.7-0ubuntu4) utopic; urgency=medium

  * SECURITY UPDATE: heap overflow and out-of-bounds read access when
    parsing DHCPv6 information
    - debian/patches/CVE-2014-3675.patch: apply proper bounds checking
      when parsing data provided in DHCPv6 packets.
    - CVE-2014-3675
    - CVE-2014-3676
  * SECURITY UPDATE: memory corruption when processing user-provided key
    lists
    - debian/patches/CVE-2014-3677.patch: detect malformed machine owner
      key (MOK) lists and ignore them, avoiding possible memory corruption.
    - CVE-2014-3677

shim (0.7-0ubuntu2) utopic; urgency=medium

  * Restore debian/patches/prototypes, which still is needed on shim 0.7
    but only detected on the buildds.
  * Update debian/patches/prototypes with some new declarations needed for
    openssl 0.9.8za update.

shim (0.7-0ubuntu1) utopic; urgency=medium

  * New upstream release.
    - fix spurious error message when fallback.efi is not present, as will
      always be the case for removable media.  LP: #1297069.
    - drop most patches, included upstream.
  * debian/patches/0001-Update-openssl-to-0.9.8za.patch: cherry-pick
    openssl 0.9.8za in via upstream.

shim (0.4-0ubuntu5) utopic; urgency=low

  * Install fallback.efi.signed as well, to lay the groundwork for fallback
    handling (wanted when we have to move a drive between machines, or when
    the firmware loses its marbles^W nvram).

Title:
  During the installation under UEFI mode, "Could not open

Status in OEM Priority Project:

  Fix Released

Bug description:
  During the installation under UEFI mode, "Could not open
  \EFI\BOOT\fallback.efi: 14" shows after passed the BIOS phase.

  I checked the source code and noticed that the messages are printed in
  function should_use_fallback(). If this function is just a detector
  then how about simply remove the output from this function to a
  provide a better user experience?

  Please refer to the attached patch.
