openwrt解压zstd包时报错"openwrt/dl/zstd-1.4.5.tar.zst: Permission denied tar: This does not look like a tar archive tar: Exiting with failure status due to previous errors"如何处理？

答: 修改zstd包的Makefile，将tar.zst替换为tar.gz

$ cat package/feeds/packages/zstd/Makefile
...
PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=https://github.com/facebook/zstd/releases/download/v$(PKG_VERSION)
PKG_HASH:=skip
