Hi, it looks like in the libutempter0:powerpc.postinst script the
chown root:root /usr/lib/utempter needs to be changed to chown root:root /usr/lib/powerpc-linux-gnu/utempter (in case anyone needs to fix it manually, edit the file in /var/lib/dpkg/info and then dpkg --configure libutempter0). Cheers -Tim
