Update Failed:due to inconsistent file permissions


When Try to update the new version of pressbook, I get the following error

“Update Failed: The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.”

Look like, some folders and files do not have proper permission.

What are the files and folders, should I look into for the permission, so that update happens from the dashboard


Google helps:


These sorts of things are general WordPress skills that aren’t really Pressbooks specific. So it’s always a good idea to search for the WordPress documentation first.
