Comment 2 for bug 1704226

Somewhat sheepishly, I have to admit that I didn't read the error message carefully at first. I think I see the issue now.

The flash disk was not clean when I started. I assumed unetbootin would wipe the disk or ignore other files. One of the other directories is named Sources. The Ubuntu Studio installer assumes this includes package repository info, but it doesn't. So it fails to parse.

It is my error (I think, will try shortly), but the behavior is not exactly graceful.

- unetbootin could warn that extraneous files could break the installer.

- or the installer could be more rigorous about ignoring directories that didn't come from the installation package.
