My best guess of what the problem is: The application is trying to install the bootloader while some buffers (linux buffers, or hardware buffers, I don't know and I don't care) are not finished writing data on the usb key.
After 10 failed attempts I finally succeeded by waiting for my usb key led to stop flashing before entering the password required for installing bootloader. so until this bug is fixed I would not recommend to run this app as root. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/859539 Title: usb-creator-gtk fails to install bootloader: "System policy prevents installing the bootloader" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/859539/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
