I'm trying to create a bootable USB stick of ubuntu-11.10-desktop-i386.iso using usb-creator-gtk on my ThinkPad X220. Usb-creator-gtk appears to work OK, but the resulting stick fails to boot either of my laptops. I tried two different USB sticks. Boot just shows a blinking cursor.
If I mount the USB stick, I see it has 729M of data on it.
One more clue: After usb-creator-gtk exits, the activity light on my USB drive continues to blink for a minute or so, and even after that's done, /media/XXXX-XXXX and /tmp/tmpXXXXXX remain mounted. I have been manually umounting them before pulling out the stick.
Is there any way to get debug output from usb-creator-gtk? Or is there a straightforward command-line alternative to usb-creator-gtk that would offer more debugging options?
UPDATE: In syslog, I noticed the error:
usb-creator-gtk[xxxxx]: segfault at 4 ip xxxxxxxxxxxxxxxx sp xxxxxxxxxxxxxxxx error 6 in libdbus-1.so.3.5.7[xxxxxxxxxxxx+xxxxx]
Turns out this is ubuntu bug #875758.
Is there an alternative to usb-creator-gtk? Ideally, a bash recipe that would help me isolate the problem and work around it?
