problem was related to the format of USB keys, in the usb-creator dialog they showed as /dev/sdb and /dev/sdc, in the backend.py there is a regular expression that was throwing out /dev/sdc and then it was expecting a number that was not there and so it throw an exception.
Once understood this (they were formatted from windows before and processed by ub8convert - http://cs.marlboro.edu/~jmajewski/eee804/Ub8convert.exe - tool) I format the usb key with gParted and then when running usb-creator I finally was able to see /dev/sdc1. Clicking on it and choosing "make startup" finally worked. In such cases a warning dialog would have been a better choice. regards, -- Dell Lattitude with 8.10 USB live crash when using usb-creator targetting another USB key https://bugs.launchpad.net/bugs/291706 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
