WordPress Permissions Update Error [resolved]

Recently I ran into a issue where an installation of WordPress, had never had any issues updating stopped being able To update via the Admin Update button.

Specifically these were the errors I would see:

 is usually due to inconsistent file permissions.: wp-admin/includes/update-core.phpinstallation Failedan Automated WordPress Update have failed to complete

The solution as it turns out are to reset the file permissions on the core files.

Provided you has SSH access to your server, the following commands may fix your issue.

Reset the permissions of all files to 664 :

664 {} \;

Reset Permissions of directories to 775 :

775 {} \;

Reset the group to the wordpress group (or whatever group makes sense for you)

Chgrp-r wordpress/path/to/site/

After running those commands I is able to successfully update for WordPress with no further issues.
