Ubuntu: Whats the simplest way to edit and add files to "/var/www"?

Question: Having installed the web server is there a simple way to set a user able to use
the graphic interface to copy files and directories to the local web server /
var/www
I gave myself administrative privileges in Ubuntu but it still doesn't allow
copies.

If you make /var/www writeable by its group and add the user to the group, that
user will not have to use sudo. Try this:
sudo adduser ＜username＞ www-data
sudo chown -R www-data:www-data /var/www
sudo chmod -R g+rwX /var/www
The user should then be able to edit /var/www/ files without hassle.
The first line adds the user to the www-data group, the second line clears up
any files with messed up ownership, and the third makes it so that all users
who are members of the www-data group can read and write all files in /var/www.
If you are logged in as ＜username＞ you need to log out and log back in for the
group membership to take effect.

You can chown, that is change the owner of that folder. This will allow you to
change the user and group of the folder, allowing your user to add/remove files
on it. To do it, replace yourusername with your name and run:
And thats it.

However, I preffer to create a virtualhost in my home folder, it's much easier.
Basically it allows you to use any folder as a apache serving folder. To show
it how it simple, lets assume that your username is username and that the
folder that you want to serve is /home/username/www
Create the following file (for instance mywebprojects) in /etc/apache2/sistes-
available replacing the username and the folder path (basically just copy and
paste and replace in #CHANGE HERE):
＜VirtualHost *:80＞

# CHANGE HERE
DocumentRoot /home/username/www

＜Directory /＞
Options FollowSymLinks
AllowOverride None
＜/Directory＞

# CHANGE HERE
＜Directory /home/username/www/＞
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
＜/Directory＞

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
＜Directory "/usr/lib/cgi-bin"＞
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
＜/Directory＞

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn

Alias /doc/ "/usr/share/doc/"
＜Directory "/usr/share/doc/"＞
Options Indexes MultiViews FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
Allow from 127.0.0.0/255.0.0.0 ::1/128
＜/Directory＞

＜/VirtualHost＞
Now lets create the www folder, add a simple hello world, disable the default
website (/var/www), enable our website mywebprojects and restart apache.
mkdir ~/www
sudo a2dissite default #
sudo a2ensite mywebprojects
sudo service apache2 restart
And that it, now you dont need to go to /var/www, you simply add files to your
www (or other givename) and it's already there :).
