Error opening file '/etc/apache2/sites-available/mysite': Permission denied

The file on disk may now be truncated!

what I should to do?

Answer 1

You need to run your editor with sudo, because site configuration files cannot be modified by users.

For example:

$ ls -l /etc/apache2/sites-available/default
-rw-r--r-- 1 root root  950 2011-06-07 14:56 default

You should try to follow the official Ubuntu Server Guide. It is a very concise and clearly written article on what you'd like to achive.

Answer 2

To fix it, use sudo to edit the file: sudo gedit /etc/apache2/sites-available/default
Then enter your password, and that's it.

gedit is one possible editor, but you can use any of them you like: vim, nano, pico, etc..
