Package: debian-installer Version: 20190302-5 Severity: normal Dear Maintainer,
I used https://cdimage.debian.org/cdimage/daily-builds/daily/20190302-5/arm64/iso-cd/debian-testing-arm64-netinst.iso to install Debian Buster on a Pine A64 LTS board. U-Boot currently does not support EFI variable at runtime. So this is the output of installing GRUB: # grub-install --target=arm64-efi --boot-directory=/boot \ --efi-directory=/boot/efi Installing for arm64-efi platform. Could not prepare Boot variable: Input/output error grub-install: error: efibootmgr failed to register the boot entry: Input/output error. # echo $? 1 The Debian installer showed an error indicating that GRUB was not installed. On boards using U-Boot this error message is misleading as GRUB is correctly installed and can be booted via U-Boot's bootefi command. It would be preferable to show a simple warning in the installer saying: "GRUB could not be registered in the boot manager." Best regards Heinrich Schuchardt
