I'm running a monte carlo code for one of my classes and the code has an option to launch a graphical plot of your input parameters. Unfortunately I'm encountering errors with launching plot window as I get an error in the terminal:
I am running Linux Mint 13 KDE on a Sony Vaio laptop. Any ideas on how to fix this?
If it helps at all, I downloaded UNetbootin the other day to make a bootable flashdrive and it failed to launch. I attempted to launch it with the terminal and it came up with the same errors.

Thanks in advance!!!

Do you have an entry in /etc/hosts ?
