app/src/fixboot/bootdoctor.cpp has explict enumeration on supported arches, and arm32 is not suppported.
Actually with a minor investigation this will fail completely on Fedora in general, the bootdoctor binary calls out to an x86 script which is full of debian/ubuntu assumptions such as: https://github.com/linuxdeepin/deepin-clone/blob/master/app/src/fixboot/scripts/boot_fix_x86.sh#L27 https://github.com/linuxdeepin/deepin-clone/blob/master/app/src/fixboot/scripts/boot_fix_x86.sh#L99 https://github.com/linuxdeepin/deepin-clone/blob/master/app/src/fixboot/scripts/boot_fix_x86.sh#L118 You could actually write a single Fedora script which would cover UEFI platforms quite well using the grub2 support in Fedora for x86_64/aarch64/ARMv7, which would be a tiny bit more than what would be required to support x86_64 well.
deepin-clone is retired since f31.
