My WordPress 4.4 updates FAIL

It’s a known issue: https://www.ads-software.com/support/topic/read-this-first-wordpress-44-master-list?replies=6&view=all#post-7760865

As of yet we have found no rhyme or reason for that to happen, but would you please provide as MUCH detail about your server as possible (OS, PHP version and flavor, etc) at https://core.trac.www.ads-software.com/ticket/34976 ?

For now, you can “update” plugins and themes by deleting and installing the latest version.
