Hi, same problem here on Debian 10.5:
Installing for x86_64-efi platform. grub-install: warning: efivarfs_get_variable: open(/sys/firmware/efi/efivars/blk0-47c7b225-c42a-11d2-8e57-00a0c969723b): No such file or directory. grub-install: warning: efi_get_variable: ops->get_variable failed: No such file or directory. grub-install: warning: efi_va_generate_file_device_path_from_esp: could not open device for ESP: Bad address. grub-install: warning: efi_generate_file_device_path_from_esp: could not generate File DP from ESP: Bad address. grub-install: error: failed to register the EFI boot entry: Bad address. @cyril: Can you point me towards the bug script that you mentioned? That way I can attach a log as well. cheers Alex
