I'm trying to install UNetbootin on Ubuntu 12.04 LTS. I downloaded the executable file from this link and followed the instructions below:

If using Linux, make the file executable (using either the command chmod +x ./unetbootin-linux, or going to Properties->Permissions and checking "Execute"), then start the application, you will be prompted for your password to grant the application administrative rights, then the main dialog will appear, where you select a distribution and install target (USB Drive or Hard Disk), then reboot when prompted.\

So I typed on my terminal sudo chmod +x unetbootin-linux-584 and tried to execute the binary file with ./unetbootin-linux-584 but got this output:

./unetbootin-linux-584: error while loading shared libraries: cannot open shared object file: No such file or directory

However when I checked for libraries libXrandr on my system I actually found them

$> locate libXrandr

so I really don't have a clue of what's the problem and how can I fix it, any ideas?

Have you tried running sudo apt-get install unetbootin in a terminal? – edwin Jun 24 '13 at 22:39

My guess is you are trying to run a 32 bit application on a 64 bit host.

unetbootin is in the repos

sudo apt-get update && sudo apt-get install unetbootin

that worked, I didn't know it was in the reps...anyways that error is weird, any idea on that? – Matteo Jun 24 '13 at 22:55
My guess is as above, what is the output of file ./unetbootin-linux-584 ? – bodhi.zazen Jun 25 '13 at 0:18
you were right! this is the output: ./unetbootin-linux-584: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, stripped. I was downloading the 32 bit version...thks so much! ` – Matteo Jun 25 '13 at 0:49
