PHP Fatal Error: Cannot redeclare Wikibase\MediaInfo\Search\closureToAnonymousClass() (previously declared in /srv/mediawiki/php-1.36.0-wmf.26/extensions/WikibaseMediaInfo/src/Search/MediaSearchProfiles.php:24)
A couple of these happened after I promoted train to group1. Sounds like a programming error to me, and so I'm treating this as a train blocker. If I'm wrong about that, please tell me or lower priority.
