 One of my WP sites (that's set to auto-upgrade to new versions) just
 failed to upgrade to 5.7.1. I got the following error messages when I
 tried to upgrade from the dashboard:
 {{{#!bash
 <?text
 Could not copy file.: wp-config-sample.php
 Installation failed.
 }}}
 When I moved a copy of that file into the root and tried again, the
 upgrade worked.
 This definitely isn't expected behaviour - and didn't occur for previous
 upgrades - and could cause confusion for others.
 This instance is running on Ubuntu 20.04 in AWS EC2.
 Thanks!
