Unpacking the package… Could not create directory. Wordpress, Apache2, Ubuntu

[admin]

This question could be all around but I have tried most answers and permission 777. But, still no luck.

<strong>/etc/apache2/sites-available/mysite.conf</strong>

<VirtualHost *:80>
        ServerName www.mysite.com
        ServerAdmin [email protected]
        DocumentRoot /var/www/html/wordpress
        ErrorLog ${APACHE_LOG_DIR}/mysite_error.log
        CustomLog ${APACHE_LOG_DIR}/mysite.log combined 
</VirtualHost>

<strong>/etc/vsftpd.conf</strong>

listen=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
allow_writeable_chroot=YES

I set permission

777

to

/usr/share/wordpress

and

/var/lib/wordpress

.
