Comment (by mlewitz):

 Hello. This may add some insight...
 I'm having the same exact issue. After upgrading to WP 4.4 I cannot update
 any plugins nor can I upgrade to 4.4.1 ...same error messages as everyone
 else.

 '''WordPress Upgrade to 4.4.1 response:'''
 {{{
 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
 }}}

 '''Attempted plugin update response:'''
 {{{
 Unpacking the update…
 Installing the latest version…
 Removing the old version of the plugin…
 Plugin update failed.

 An error occurred while updating Akismet: Could not create directory.
 /public_html/wp-content/plugins/akismet/
 }}}


 I have been finding messages like this in my '''apache error logs''' since
 the issue began:
 (This produced consistently when attempting to upgrade from 4.4 to 4.4.1)
 Note: '''THIS IS A MULTISITE INSTALLATION'''

 {{{

 }}}

 Note: "blog_resrc_" is not the real prefix.
 Before upgrading to 4.4 everything worked just fine.
 All file/folder permissions are set correctly and are unchanged since the
 4.4 upgrade.

 My server (GoDaddy VPS):
 CentOS 6 + cPanel
 Apache 2.4.16
 PHP 5.5.30
 MySql 5.6.28

 Hopefully this helps!
