We get this on trying to build images locally:
W: GPG error: https://packages.sury.org/php bookworm InRelease: The following signatures were invalid: EXPKEYSIG B188E2B695BD4743 DEB.SURY.ORG Automatic Signing Key <deb@sury.org> 2026-02-17 15:59:28 INFO docker_pkg.do_build.bookworm-php83-fpm: E: The repository 'https://packages.sury.org/php bookworm InRelease' is not signed.
Should untangle what's going on here and make sure these images build cleanly, and/or dispense with them and do T407430: Upgrade MediaWiki-Docker PHP images to PHP 8.5.
