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

Thank you for your help resolving these issues!
