The 1.34.0-wmf.20 version of MediaWiki is blocked.
https://phabricator.wikimedia.org/T220745
The new version is not deployed anywhere yet. It will not be deployed until these issues are resolved:
* ServiceContainer.php: Circular dependency when creating MobileFrontend service "AMC.UserMode > AMC.Manager > FeaturesManager > UserModes > AMC.UserMode" https://phabricator.wikimedia.org/T231014 * DefaultPreferencesFactory.php: Global default '' is invalid for field incubatortestwiki-code https://phabricator.wikimedia.org/T231029 * /w/api.php... ErrorException from line 0 of : PHP Notice: Unable to unserialize ... Size of serialized string ... exceeds max https://phabricator.wikimedia.org/T231071 * L10n cache is completely broken https://phabricator.wikimedia.org/T231183
Once these issues are resolved train can start.
Additionally, I've found this errors in logs, but since they are not new, they are not blocking the train.
* Assert.php: Bad value for parameter $responses: must have as many responses as requests https://phabricator.wikimedia.org/T231023 * Assert.php: Bad value for parameter $oldContent: must be a TextContent|null https://phabricator.wikimedia.org/T231084 * WikibaseClient.php: PHP Notice: Undefined index: https://phabricator.wikimedia.org/T231089
Thank you for your help resolving these issues!
