Can you confirm the following file exists in your mirror? /import/mirrors/CentOS/stx-r1-centos75/CentOS/pike/Binary/LiveOS/squashfs.img If the file does exit, very likely it was *corrupted* because it seemed the failure came from: mount -o loop -t squashfs $ORIG_SQUASHFS $work_dir/squashfs.mnt in script: "~/cgcs-root/build-tools/make-installer-images.sh" You can manually mount "squashfs.img" to confirm it is not corrupted.
