Fresh LAMP server setup with Ubuntu 12.04 and VSFTPD.

I'm trying to access the /var/www folder (web root) with FTP user.

I created a new user ftpuser and added it to the www-data user group created automatically by Apache.

Home directory of that user is set to /var/www.
I also changed the ownership of the /var/www to www-data group and changed permissions to 02775.

However, I'm still not able to upload files. Error is: "553 Could not create file".

1. Can someone please explain me how to set these permissions properly?


2. What is the correct setup? Should I set the home directory of ftpuser to /var/www or somehow diffeerently?

I found a lot of topics on the web but none of them offer a universal solution.

Thank you!

UPDATE:

Here is the output of ls -l of /var/www:

drwxr-sr-x 3 root ftpuser 4096
