compile rootfs error: chroot: failed to run command ‘mount’: Exec format error

我的编译环境是： ubuntu 18.04 x64
编译rootfs时报错如下：
Extracting ... OK
chroot: failed to run command ‘mount’: Exec format error
chroot: failed to run command ‘mount’: Exec format error
chroot: failed to run command ‘/second-phase’: Exec format error
这个错误产生在以下位置：
文件路径：scripts/lib/distributions.sh
do_chroot() {
# Add qemu emulation.
cp /usr/bin/qemu-arm-static "$DEST/usr/bin"
cmd="$@"
chroot "$DEST" mount -t proc proc /proc || true
chroot "$DEST" mount -t sysfs sys /sys || true
chroot "$DEST" $cmd
chroot "$DEST" umount /sys
chroot "$DEST" umount /proc

    # Clean up
    rm -f "$DEST/usr/bin/qemu-arm-static"
}

能告诉我怎么解决这个问题吗？是qemu的问题吗

Try reinstall qemu-user-static

sudo apt purge qemu-user-static
sudo apt install qemu-user-static
