it would appear that checkbox-gtk, which is the graphical interface for the system testing application, isn't installed. Did you perhaps uninstall it at some point? You could try to open a terminal window and install checkbox-gtk: sudo apt-get install checkbox-gtk Please let me know if you're able to run system testing after doing this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769258 Title: system testing doesn't work on 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
