This also affects the 18.04.1 "alterantive installer (debian-installer), where I reproduced it today.
This error will not occur on the current default server installer (Subiquity) at this time since it does not support dmcrypt-luks at all. To my knowledge, the desktop installer (Ubiquity) does not support dmcrypt-luks FDE incl. /boot), so it will not occur there either. To work around this issue, after d-i reports that grub-install failed, choose to 'continue', confirm that you will have to live without a boot loader. Then press escape or select 'go back', which brings up the installers' main menu. There, select to 'run a shell' (one of the latter options), then: # Mount the EFI system partition (ESP) you defined during manual partitioning ( usually /dev/sda1 - double-check this using: blkid -t TYPE=vfat ) to /target/boot/efi: mount /dev/sda1 /target/boot/efi mount --bind /dev /target/dev mount --bind /dev/pts /target/dev/pts mount --bind /sys /target/sys mount --bind /sys/firmware/efi/efivars /target/sys/firmware/efi/efivars mount --bind /run /target/run # needed for resolver chroot /target /bin/bash echo GRUB_ENABLE_CRYPTODISK=y >> /etc/default/grub apt update apt purge grub-efi-amd64-signed # unfortunately, to this date, this lacks the grub "cryptodisk" command required to decrypt LUKS and we have to resort to the unsigned grub variant apt --purge autoremove apt install grub-efi-amd64 update-initramfs -k all update-grub grub-install /dev/sda # this may be different for you, choose the storage device which contains the ESP exit umount /target/run umount /target/sys/firmware/efi/efivars umount /target/sys umount /target/dev/pts umount /target/dev umount /target/boot/efi exit This brings you back into the installer, from where you can continue from the step after "install bootloader". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762988 Title: Bootloader installation fails on UEFI systems with FDE (incl. /boot) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1762988/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
