Thanks for your report.
This is due to the postinst script using bash syntax but being with /bin/sh (dash) To workaround this open a terminal and run the following commands: $ sudo rm /etc/ssl/certs/stone.pem $ sudo bash -x /var/lib/dpkg/info/stone.postinst configure
Don't hesitate to submit any new bug.
