I have tested latest Turboprint 1.96-4 on Ubuntu Hardy Heron beta. It does not work. I am not shure if it is the latest CUPS, or the AppArmor installed by default that is causing this problem. Will 1.96 support Hardy Heron?
I also am having the same problem. I did an upgrade from 7.10 and now turboprint fails to start. I have tried re-installing (no errors) but the setup/config files fail to launch.
