It is possible that /etc/mumble-server.ini will not be present on upgrades, in which case postinst would fail. Please verify that the file exists by doing something like this instead:
if [ -f /etc/mumble-server.ini ]; then
chmod 0640 /etc/mumble-server.ini || true
chown root:mumble-server /etc/mumble-server.ini || true
fi
Thanks for the debdiff!
