hey all, i've been having some troubles with apache. this is my first time running anything but windows, so i'm still a little new all things ubuntu. I set up apache using $ sudo apt-get install apache2 (or something along those lines), and everything went smoothly. i went in (to /var/www/) to try to edit the files being served, but i keep being told that i don't have permissions. i'm a bit confused as to how the only person who uses the computer (and has administrative power everywhere) doesn't have permissions...plus, i can't even view the files. going to http://localhost returns a 403 error. any help would be greatly appreciated.thanks in advance!
