在构建 openstlinux-5.4-dunfell-mp1-20-06-24 时，我总是遇到以下错误：
- ERROR: st-image-resize-initrd-1.0-r0 do_rootfs: The postinstall intercept hook 'update_desktop_database' failed, details in /mnt/data/dist-pack/openstlinux-5.4-dunfell-mp1-20-06-24/build-openstlinuxweston-STM32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueabi/st-image-resize-initrd/1.0-r0/temp/log.do_rootfs

日志文件包含以下内容：

为什么找不到 `update-desktop-database` 命令？我该如何解决这个问题？
非常感谢。
亲切的问候！
