Public bug reported: I tried to install Xubunti 18.04.1 LTS on a HP T610 Plus thin client with the 1.20 Rev A BIOS (recently upgraded from 1.16 Rev A).
The installation proceeded normally until the bootloader was installed -- grub-install failed. I ran grub-install a second time from a console and got the same error as seen in the installer: <pre>$ sudo chroot /target grub-install /dev/sda Installing for x86_64-efi platform. Could not delete variable: Invalid argument grub-install: error: efibootmgr failed to register the boot entry: Block device required. </pre> ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubiquity 18.04.14.6 ProcVersionSignature: Ubuntu 4.15.0-29.31-generic 4.15.18 Uname: Linux 4.15.0-29-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CasperVersion: 1.394 Date: Wed Aug 8 19:23:41 2018 InstallCmdLine: BOOT_IMAGE=/casper/vmlinuz file=/cdrom/preseed/xubuntu.seed boot=casper quiet splash --- LiveMediaBuild: Xubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) SourcePackage: grub-installer UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: grub-installer (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic ubiquity-18.04.14.6 xubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786090 Title: Installation fails on HP T610 Plus Thin Client internal flash (EFI) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1786090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
