Hi Willem, Thank you for taking the time to report this issue and helping to make Ubuntu better.
Please try the following steps to start a fresh test: 1- Go to Places (on the top panel / menu bar) -> Home Folder 2- When a file browser opens, select "View -> Show hidden files". 3- A bunch of hidden directories will appear. Please open the .cache directory. 4- From that directory, please drag the "checkbox" subdirectory to the trash, or right-click it and select "Move to trash". Once you've done this, the previous run you refer to will be removed and you can start a new round of testing. Please let me know if this solves your problem. ** Changed in: checkbox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/724540 Title: System testing only worked once -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
