Not when installing linux-signed-image-generic itself, but when installing the shim-signed package or when the fglrx-updates-core package builds its dkms module, yes there should be a series of questions asked about disabling secureboot. > Under 3.13.0-91, sudo modprobe fglrx-updates goes through without comment. > Under 3.13.0-92, sudo modprobe fglrx-updates fails with ERROR: could not > insert fglrx_updates: required key not available. > I don't know how this could be, since > 3.13.0-92-generic/updates/dkms/fglrx_updates.ko is signed with the same > key as 3.13.0-91-generic/updates/dkms/fglrx_updates.ko. This is because 3.13.0-91-generic doesn't enforce kernel signature verification, so it will load the module with a warning in dmesg about it being unverified and the kernel being 'tainted', whereas 3.13.0-92-generic does enforce kernel signature verification and rejects this module because it's not signed by a *trusted* key. To have the kernel trust the key you used for signing, you must enroll it in the firmware in either the SecureBoot database or the MOK database. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1603655 Title: After update, xorg will not boot Status in linux package in Ubuntu: Confirmed Bug description: Last night, Ubuntu Software Updater installed a round of updates. I shut down my computer, and when I booted this morning, the GUI failed to load or run at all. I switched to a terminal with Ctrl+Alt+F1, which worked fine. I tried rebooting into 3.13.0-91 via GRUB, at which point the GUI worked fine. Examining Ubuntu Software Center History, the new linux-image stood out, so I tried uninstalling that first. The command I ran was: sudo apt-get remove linux-image-extra-3.13.0-92-generic:amd64 linux-image-3.13.0-92-generic:amd64 linux-signed-image-3.13.0-92-generic:amd64 && sudo apt-get install linux-image-extra-3.13.0-91-generic:amd64 linux-image-3.13.0-91-generic:amd64 linux-signed-image-3.13.0-91-generic:amd64 My machine works fine now (with the old linux-image), but I thought I should inform you of the problem with the new linux-image. P.S. Since xorg is involved I tried to use ubuntu-bug xorg as the instructions said, but there was no way to enter an explanation, and reporting system information with no explanation *now* when my system is *working* would be completely misleading. There seems to be no way to attach any text or message to an ubuntu-bug report. I have attached the output from apport-bug --save=bugfilename linux-image-3.13.0-92-generic:amd64. --- ApportVersion: 2.14.1-0ubuntu3.21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: david 1900 F.... pulseaudio /dev/snd/controlC0: david 1900 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=907fdd35-197c-4341-9daa-c29636443fb6 InstallationDate: Installed on 2014-06-06 (773 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Hewlett-Packard HP Pavilion 17 Notebook PC NonfreeKernelModules: fglrx Package: linux (not installed) ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-91-generic.efi.signed root=UUID=1fe70a4d-bce2-4bc1-921f-d793500b9af8 ro quiet splash crashkernel=384M-:128M vt.handoff=7 ProcVersionSignature: Ubuntu 3.13.0-91.138-generic 3.13.11-ckt39 RelatedPackageVersions: linux-restricted-modules-3.13.0-91-generic N/A linux-backports-modules-3.13.0-91-generic N/A linux-firmware 1.127.22 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: trusty Uname: Linux 3.13.0-91-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 11/11/2014 dmi.bios.vendor: Insyde dmi.bios.version: F.35 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 1984 dmi.board.vendor: Hewlett-Packard dmi.board.version: 01.15 dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.35:bd11/11/2014:svnHewlett-Packard:pnHPPavilion17NotebookPC:pvr0880100021305B10000620100:rvnHewlett-Packard:rn1984:rvr01.15:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.name: HP Pavilion 17 Notebook PC dmi.product.version: 0880100021305B10000620100 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603655/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
