Hello there, I'm a beginner Ruby on Rails Programmer and I'm trying to install Apache2 + Passenger(That's for Rails Deployment).. and at the end of the installation process, Passenger gave me a few lines to add to the file apache2.conf at /etc/apache2/ but I can't override this file.. I have no permission =( I've also uploaded an image showing me the error.
P.S => I'm logged into Ubuntu with my username and password.
Please help! and thanks, Rodrigo.
