I am running wordpress 4.0 on Cent OS powered VPS. The installation runs smoothly, in my admin dashboard I see updates for wordpress/plugins/themes .I am facing the following errors when I try to upgrade them from dasboard Updating Wordpress to 4.1 from 4.0 UpdateWordPress Downloading update from https://downloads.wordpress.org/release/wordpress-4.1-new-bundled.zip… Unpacking the update… Couldnot create directory.

All updates have been completed. I know I am messing with the file permissions, I have tried setting the permissions for the files as well. I tried assigning them to various groups/users like apache,root and nginx. These are the current file permissions for my wordpress directory. -rwxr-xr-x 1 apache apache 3070Jan210:59 wp-config.php drwxr-xr-x 12 apache apache 4096Jan123:31 wp-includes drwxrwxrwx 6 apache apache 4096Jan122:37 wp-content drwxr-xr-x 9 apache apache 4096Jan122:31 wp-admin -rwxr-xr-x 1 apache apache 435Jan122:25 index.php-rwxr-xr-x 1 apache apache 19930Jan122:25 license.txt-rwxr-xr-x 1 apache apache 7290Jan122:25 readme.html-rwxr-xr-x 1 apache apache 3824Jan122:25 sitemap.backup.xml-rwxr-xr-x 1 apache apache 5082Jan122:25 wp-activate.php-rwxr-xr-x 1 apache apache 289Jan122:25 wp-blog-header.php-rwxr-xr-x 1 apache apache 5110Jan122:25 wp-comments-post.php-rwxr-xr-x 1 apache apache 2826Jan122:25 wp-config-sample.php-rwxr-xr-x 1 apache apache 3071Jan122:25 wp-cron.php-rwxr-xr-x 1 apache apache 2460Jan122:25 wp-links-opml.php-rwxr-xr-x 1 apache apache 2787Jan122:25 wp-load.php-rwxr-xr-x 1 apache apache 34185Jan122:25 wp-login.php-rwxr-xr-x 1 apache apache 8512Jan122:25 wp-mail.php-rwxr-xr-x 1 apache apache 11489Jan122:25 wp-settings.php-rwxr-xr-x 1 apache apache 27005Jan122:25 wp-signup.php-rwxr-xr-x 1 apache apache 4153Jan122:25 wp-trackback.php-rwxr-xr-x 1 apache apache 3132Jan122:25 xmlrpc.php Please guide me for suitable permissions.
