I am a beginner Ruby on Rails Programmer and I am attempting to install Apache2 + Passenger(That's for Rails Deployment).. and also at the finish from the installation process, Passenger offered me a couple of lines to increase the file apache2.conf at /etc/apache2/ however i can't override this file.. I've no permission =( I have also submitted an image showing me the mistake.

P.S => I am drenched into Ubuntu with my account information.

Help! and thanks, Rodrigo.

The easiest strategy is to spread out the file using the sudoedit program, as with

sudoedit /etc/apache2/apache2.conf

that will prompt for the password after which open your editor.
