[Pharo-project] Unable to run pharo on Ubuntu 12.10

I try to double click the Pharo-1.4-one-click.sh , even after going to properties and enabling allow excuting file as programm does nothing. And running from terminal prints the following exloupis@ephestos:~/Downloads/Pharo-1.4-one-click.app$ sudo ./Pharo-1.4-one-click.sh ./Pharo-1.4-one-click.sh: line 26: /home/exloupis/Downloads/Pharo-1.4-one-click.app/Contents/Linux/pharo: Permission denied ./Pharo-1.4-one-click.sh: line 26: exec: /home/exloupis/Downloads/Pharo-1.4-one-click.app/Contents/Linux/pharo: cannot execute: Permission denied Any idea why ?
