I have used it for iso-testing of trusty, utopic and vivid - so I know
that it is compatible with Ubuntu and Lubuntu.

I tested to install Lubuntu 15.04 from the desktop 32-bit bit iso file
with usb-creator-gtk in a system installed from

ubuntu-14.04.2-desktop-amd64.iso

added

deb http://archive.ubuntu.com/ubuntu/ trusty-proposed restricted main
multiverse universe

to

/etc/apt/sources.list

and updated/dist-upgraded to make the system completely up to date.

This bug affected the installation before adding the proposed
repository. The version of usb-creator-gtk from 'proposed' fails to
install the bootloader. The version that comes with 14.04.2 LTS could
install the bootloader but suffers from this bug (1325801).

I tried again after wiping the drive separately (new partition table and
new FAT32 partition), unmount, un-plug and re-plug the pendrive for usb-
creator-gtk to work, but it failed again. I started with the installed
system running via USB 3, which works with Unetbootin and mkusb. I moved
the SSD to the internal bay, and tried again, but I still had the same
problem.

Maybe this is a problem with the authentication method? Or a problem
with chroot (if that is used)?

Anyway, I tried to boot from the pendrive, which seems to have 'all the
files' but not the bootloader. But it does not work, I get a flashing
cursor at the top left corner of the screen.

Finally I tried to create a pendrive without persistence. But usb-
creator-gtk still fails when trying to install the bootloader.

I do not feel authorized to change any tag.
