Wordpress upgrade to 4.4.2 failed

My setup:

OS: CentOS 7.1
http user: apache
http group: apache

When i perform automatic update, I get below error:

Downloading update from https://downloads.wordpress.org/release/wordpress-4.4.2-new-bundled.zip…

Unpacking the update…

The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

Installation Failed

I have tried upgrade with full permission but no luck:

#find . -type f -exec chmod 666 {} \;
#find . -type d -exec chmod 777 {} \;

Anyone has any clues? I searched for hours but no luck.

Do Not use 777 permission! Wordpress only need 755 for directories, 644 for files, and 666 for themes and plugins directories & files. And you could give 600 to wp-config.php for security. You can see Wordpress documentation for file permission

I had this problem, and this is how I solved the issues.

  • Make sure all owned by Apache.
    sudo chown -R apache:apache /var/www/html/sitedir

  • Give proper permissions
    sudo find /var/www/html/sitedir -type d -exec chmod 755 {} +
    that would give 755 permission to all directory inside sitedir
    sudo find /var/www/html/sitedir -type f -exec chmod 644 {} +
    that would give 644 to all files
    sudo find /var/www/html/sitedir/wp-content/themes -type f -exec chmod 666 {} +
    sudo find /var/www/html/sitedir/wp-content/plugins -type f -exec chmod 666 {} +
    those two commands above make 666 permission to all files inside themes and plugins directory

  • If you use selinux
    sudo chcon -R system_u:object_r:httpd_sys_content_t:s0 /var/www/html/sitedir
    sudo chcon -R system_u:object_r:httpd_sys_rw_content_t:s0 /var/www/html/sitedir/wp-content
    Two commands above would change the context of your files and directories. And restart php-fpm if you use one.

    UPDATE:
    If you don't get through until this point. You might also need to set a local policy module for selinux. sudo grep php-fpm /var/log/audit/audit.log | audit2allow -M mypol
    sudo semodule -i mypol.pp
    Then restart php-fpm.

I also cover this Wordpress permission issue more detail on my blog :)

I ended up upgrading manually which worked smoothly.

Sometimes some (security) plugins seem to interfere with updating older versions of WordPress. Try deactivating plugins and trying again.

If all else fails, just perform a manual update via FTP.
