Write permissions in /var/www folder

Question

I followed the steps from https://askubuntu.com/a/51337/115811 to add my user to a www-data group and set the /var/www/ dir group writeable.

sudo adduser <username> www-data
sudo chown -R www-data:www-data /var/www
sudo chmod -R g+rw /var/www

This is /var/www/ contents:

drwxrwsr-x  2 www-data www-data 4096 Oct 25 08:13 ./
drwxr-xr-x 14 root     root     4096 Oct 17 08:47 ../
-rwxrwsr-x  1 www-data www-data  177 Oct 17 23:51 index.html*

However when I try to git clone or mkdir in /var/www/, I am still getting "Permission denied". What am I missing?

Solution

this line sudo chown -R www-data:www-data /var/www made the directory to user www-data so other user can't write, why not try something like chown -R :www-data /var/www

Can you post the output of the command groups with your user <username>, that should have access?

@nickanor Perhaps you could add that as an answer?

be careful when you use 777 permission. Your folders or files will be accessed by everyone. For security reason this is not recommended.
