We had this already, there was similar bug. Does the prob persist when you just re-install qemu-user-static package using dpkg (without removing it first)? The question here is that update-binfmt does not refresh changed definitions at the first run. > > # file debian-jessie-ppc64el/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1 > debian-jessie-ppc64el/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1: ELF > 64-bit LSB executable, 64-bit PowerPC or cisco 7500, version 1 (GNU/Linux), > dynamically linked, interpreter /lib64/ld64.so.2, for GNU/Linux 2.6.32, > BuildID[sha1]=3bea2777c40886422ecd521a04141dbeeb194afb, stripped > # objdump -f debian-jessie-ppc64el/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1 > > debian-jessie-ppc64el/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1: file > format elf64-little > architecture: UNKNOWN!, flags 0x00000112: > EXEC_P, HAS_SYMS, D_PAGED > start address 0x0000000010117ec8 Please dump first 64 bytes of the executable using hexdump -C -- hexdump -C -l 64 debian-jessie-ppc64el/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1 (64bytes is a bit more than needed, but I don't have elf header layout handy and don't remember the size needed). Interesting is that it says architecture is unknown. Thanks, /mjt
