Bug Description
The official Ubuntu Netbook Remix ISO image seems corrupted. It doesn't work with usb-creator (which is extremely annoying as it is supposed to be the official way to install it) bceause isoinfo says it is corrupted; file-roller cannot fully extract it as well.
Steps to reproduce:
1) Download official "ubuntu-
2) Run usb-creator
3) Click on "other..."
4) Select iso image
The iso image is not added to the window. What happens is that the "isoinfo" utility says that the ISO is somewhat invalid, and usb-creator doesn't display the error message (there's another launchpad bug for this).
This is the problem:
$ isoinfo -J -i ubuntu-
isoinfo: Short read on old image
The above command line is what usb-creator is running (confirmed with strace).
If I open the iso file with file-roller and try to view the "/.disk/info" file, I get this error instead:
7-Zip 9.04 beta Copyright (c) 1999-2009 Igor Pavlov 2009-05-30
p7zip Version 9.04 (locale=
Processing archive: /home/rasky/
Extracting .disk/info Data Error
Sub items Errors: 1
So basically at least two independent programs agree that the ISO file is "corrupted". The fact that the OFFICIAL usb-creator utility cannot read it is annoying and embarassing, since that is the official documented way to install UNR.

I assign this bug to the usb-creator package. Have you checked the MD5 of the ISO image?
