With how the images are compiled, there appears to be a faulty step that adds trailing garbage (some fake certificate).

Given that these .img.gz files are made by piping data, the compressor does not have sufficient information to write a suitable header in the gzip describing file length, and the decompression fails with some gzip utilities. The GZIP RFC spec makes no allowances for trailing data. So the Makefile portions that directly produce gzip must remove the erroneous pipes that include trailing garbage: IMAGE/combined.img.gz := grub-config pc | combined | grub-install | gzip | append-metadata IMAGE/combined-efi.img.gz := grub-config efi | combined efi | grub-install efi | gzip | append-metadata See also https://github.com/openwrt/openwrt/pull/16553 _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
