`executable-not-elf-or-script`

This executable file is not an ELF format binary, and does not start with the #! sequence that marks interpreted scripts. It might be a sh script that fails to name /bin/sh as its shell, or it may be incorrectly marked as executable. Sometimes upstream files developed on Windows are marked unnecessarily as executable on other systems.

If you are using debhelper to build your package, running dh_fixperms will often correct this problem for you.
