Could not write the disk image (/media/hack_den/Alpha_0419/data/distro/tuxlinux-x86-dist.iso) to the device (/dev/sdd)

Solution 1:

@manolius’s suggestion worked for me. Add sudo to the command:

sudo usb-creator-gtk

This is because USB Creator needs to:

  • Install a boot loader
  • Format a device
  • Image a device
  • Mount a device

Most of these actions require root, as block devices are owned by root.
