[Bug 1123403] Re: Installer is blocked by UEFI Secure Boot
I've confirmed that the 64-bit saucy daily build from 2013-09-20 fails
to boot with this message:
1. USB HDD: SanDisk has been blocked by the current security policy.
[Ok]
Retrying with secure boot disabled allows it to boot without error.
** Changed in: linux (Ubuntu Saucy)
Status: Incomplete => Confirmed

Title:
Installer is blocked by UEFI Secure Boot
Status in “linux” package in Ubuntu:
Confirmed
Status in “linux” source package in Saucy:
Confirmed
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.
[Ok]
I have confirmed that the USB stick boots without error when I enable
the legacy BIOS boot mode on the computer's setup screen.
