  Installer is blocked by UEFI Secure Boot

Status in “linux” package in Ubuntu:
Status in “linux” source package in Saucy:

Bug description:
  The release notes for Ubuntu 12.10 claim [1] that UEFI Secure Boot is
  supported and suggest that I should expect an "it just works"
  experience on new hardware.

  However, when I try to boot an Ubuntu 12.10 64-bit bootable USB stick
  [2] on a brand-new Acer Aspire V5-171, the following message appears:

      2. USB HDD: Memorex TD Classic 003C has been blocked by the current security policy.

  I have confirmed that the USB stick boots without error when I enable
  the legacy BIOS boot mode on the computer's setup screen.
