Unable to start unetbootin

Question

When trying to start unetbootin from the terminal using unetbootin, I get the following output:

I get the prompt asking for my password but then nothing happens and when started using sudo unetbootin, the output is:

unetbootin: cannot connect to X server 

I have tried the following, but to no avail:

• Bug report on Launchpad
• Seemed to be a similar problem

I am unable to report the version of unetbootin as neither unetbootin -v nor unetbootin --version are valid options and the man page does not information on doing this.

Is there a workaround to this?

Answer 1

This did not resolve until this answer was written, but the main purpose of me using unetbootin was to make a Windows bootable, which can be done using winusb.

To install winusb:

sudo add-apt-repository ppa:colingille/freshlight
sudo apt-get update 
sudo apt-get install winusb

It has a very intuitive UI, so making a windows bootable shouldn't be hard.
