Не удается получить доступ к папке из-за неправильных команд CHMOD

Я не смог просмотреть мой собственный vhost www.ajweb.dev в моем apache2.

Моя папка www находилась в / home / ajinkya / www

Так что я сделал следующее.

ajinkya@ajinkya-Inspiron-3521:~$ cd www
ajinkya@ajinkya-Inspiron-3521:~/www$ chmod 755 ./www
chmod: cannot access `./www': No such file or directory
ajinkya@ajinkya-Inspiron-3521:~/www$ chmod 755 ../www
ajinkya@ajinkya-Inspiron-3521:~/www$ sudo chmod 755 ../www
ajinkya@ajinkya-Inspiron-3521:~/www$ sudo useradd -g www-data ajinkya
useradd: user 'ajinkya' already exists
ajinkya@ajinkya-Inspiron-3521:~/www$ sudo chown -R www-data /home/ajinkya/www
ajinkya@ajinkya-Inspiron-3521:~/www$ sudo service apache2 restart

И теперь я не могу просматривать / открывать эту папку вручную.

ls -l /home/ajinkya | grep www
