  • Component changed from General to Upgrade/Install
  • Milestone changed from Awaiting Review to 5.9

Hi there, thanks for the ticket!

This appears to be an issue with WP-CLI incorrectly deleting files on case-insensitive filesystems when an update changes the case of a file, e.g. from Requests\IRI.php to Requests\Iri.php.

See #54504 and the upstream issue for more details:

Moving to the milestone for more visibility, though at this point the changes are required in WP-CLI and not in core.

Thanks for your reply, @SergeyBiryukov. The problem indeed only happens when using WP-CLI. When using the [WordPress Beta Tester](, I could update to 5.9 Beta 1, as expected.

  • Milestone changed from 5.9 to 6.0

Decision was made to revert Requests 2.0.0 and punt it and all associated tickets to WordPress 6.0. Why? There are 2 issues in the upgrader process that need resolution. Though this ticket is for upstream WP-CLI, Core has the same problem detecting case-insensitive filesystems. Moving this ticket along with the others to 6.0 for investigation and thorough testing. Will keep this ticket open until the issue is resolved in WP-CLI.

#8 @afragen

I believe this issue was fixed in WP-CLI 2.6.0, which happens to be included in latest LocalWP.
