Public bug reported: During installation of Trusty on a RAID6/LVM system, the installation fails during the "configure" phase of grub-efi-amd64. The installer message says "GRUB installation failed The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot."
The installer log message screen says (among other things): grub-install: error: cannot open `/boot/grub/x86_64-efi/load.cfg': No such file or directory. After issuing: chroot /target grub-install -v ... the installation of grub also ends with: grub-install: info: copying `/boot/grub/x86_64-efi/load.cfg' -> `/boot/efi/EFI/ubuntu/grub.cfg' grub-install: error: cannot open `/boot/grub/x86_64-efi/load.cfg': No such file or directory Installation is on a raid6 (software-raid) device with lvm, /dev/mapper /volumegroup-root1404 is the root-fs (ext4 formatted), there is a separate EFI partition on /dev/sda. The disks are GPT-partitioned. ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1298399 Title: grub-efi-amd64 2.02~beta2-7 fails to install on raid/lvm To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1298399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
