Bug Description

Binary package hint: usb-creator

usb-creator-gtk version: 0.2.12
Ubuntu 9.10

When the path to ISO-file contains non-ascii Unicode characters, usb-creator-gtk fails with "installation failed".

[SRU request]
users cannot create usb startup disk unless moving ISO.
ISO files are downloaded to xdg-downloads directory, and translated xdg-downloads directory's name usually contains non-ASCII characters.
users who want to make Lucid startup disk on Karmic machine may face this error.

fixed in version 0.2.21
and exact change is the following:

1. Move ISO to "/home/user/DIRECTORY_NAME/ubuntu-9.10-desktop-i386.iso" (DIRECTORY_NAME contains non-ascii character)
2. Launch usb-creator-gtk and select the ISO
3. Press "Make Startup Disk"
4. Get "Installation failed" message

Expected result:
Press "Make Startup Disk",
then start writing to USB stick
and done.

I faced the same problem.
I added my .usbcreator.log.

Log file ends with the line,
"TypeError: execv() arg 2 must contain only strings"

"Downloads" folder is translated to each languages.
And ISO images are downloaded to "Downloads" directory.
So, many users may face this problem.

Same problem, which is a bit annoying because in French, the default download directory is "Téléchargements", so if I download a .iso (using bittorrent), and try to put the .iso on the key, it doesn't work (and no information is given about the cause).

In Swedish the default download directory is "Hämtningar".

Also affected.

This bug is not likely to be fixed in karmic since it's a consequence of a python 2.x bug.

Fixing it would require one of the following:

. patch python
. patch usb-creator to warn user (lame and easy)
. rename the file on-the-fly (ugly)
. patch usb-creator not to use Subprocess.Popen (would create other issues)
. wait for python3

Just lost a few hours because of this bug. My system is in French and the process would fail with "Installation failed" message and nothing else..

Took me a while to find the error in the log.

I understand this is a python bug and that is fine, but the process should at least fail with a more useful error message or a pointer to the log file!

Unbelieavable! :D
I never thought it will be the name of the directory!
Mine is in Greek...

I agree with Cedric Veilleux. If i knew where the log is, i would have save much time..

I second the opinions of Veilleux and Kapernaros, a simple description of where to find the log will save many hours until a fix is possible.

Nominating for SRU, fulfills: (1) have an obviously safe patch and (2) affect an application rather than critical infrastructure packages

It seems this bug reappeared on Ubuntu 13.10. Using usb-creator-gtk 0.2.23, I can reproduce the problem when trying to use an iso image located in the downloads folder (LANG=fr_CA.UTF-8): ~/Téléchargements/. If I move the iso to ~/, which contains no special character, then the error is resolved. I also tried with other directory names containing special characters and it failed in the same way. Could someone reopen this bug?
