** Description changed: shim-signed package installs with no error with apt upgrade, but then the system cannot boot afterwards with secure boot enabled. System hangs indefinitely on UEFI manufacturer logo screen (Dell in this case), not getting as far as grub. Disabling secure boot is a workaround. Rolling back to previous shim-signed version 1.46+15.4-0ubuntu1 fixes the problem (system can once again boot with secure boot enabled). Done this for now to allow secure boot to be enabled: $ sudo apt install shim-signed=1.46+15.4-0ubuntu1 $ sudo apt-mark hold shim-signed Details of system where problem is observed: - Dell XPS 13 7390 laptop - Intel® Core™ i7-10510U CPU / 16GB RAM - BIOS/UEFI firmware version: v1.8.0 (latest) - Ubuntu hirsute 21.04 64bit (Linux only, single OS, not dual booting) - Kernel version: 5.11.0-22-generic - GRUB: 2.04-1ubuntu45 Any questions / additional info, please ask. + --- + ProblemType: Bug + .proc.sys.kernel.moksbstate_disabled: Error: [Errno 2] No such file or directory: '/proc/sys/kernel/moksbstate_disabled' + ApportVersion: 2.20.11-0ubuntu65.1 + Architecture: amd64 + CasperMD5CheckResult: unknown + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 21.04 + EFIBootMgr: + BootCurrent: 0000 + Timeout: 0 seconds + BootOrder: 0000,0001 + Boot0000* ubuntu HD(2,GPT,cc31568c-2d13-40c3-8cfe-a0d889852837,0x800,0x32000)/File(\EFI\ubuntu\shimx64.efi) + Boot0001* UEFI CT1000P1SSD8 1917E1FE1D9D 1 PciRoot(0x0)/Pci(0x1d,0x4)/Pci(0x0,0x0)/NVMe(0x1,00-00-00-00-00-00-00-00)/HD(2,GPT,cc31568c-2d13-40c3-8cfe-a0d889852837,0x800,0x32000)/File(\EFI\Boot\BootX64.efi)N.....YM....R,Y. + EcryptfsInUse: Yes + InstallationDate: Installed on 2020-01-26 (540 days ago) + InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) + Package: shim-signed 1.46+15.4-0ubuntu1 + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 5.11.0-22.23-generic 5.11.21 + SecureBoot: 6 0 0 0 1 + Tags: hirsute wayland-session + Uname: Linux 5.11.0-22-generic x86_64 + UpgradeStatus: Upgraded to hirsute on 2021-05-29 (51 days ago) + UserGroups: adm cdrom dip docker lpadmin lxd plugdev sambashare sudo + _MarkForUpload: True ** Attachment added: "BootEFIContents.txt" https://bugs.launchpad.net/bugs/1936759/+attachment/5511923/+files/BootEFIContents.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936759 Title: shim-signed 1.48+15.4-0ubuntu5 does not secure boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1936759/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
