Breaking: #92457 - Extension Repository database table removed

See forge#92457


The existing extension manager had functionality to add multiple repositories by adding new database rows into the database table tx_extensionmanager_domain_model_repository.

Because this functionality has been superseded by a configurable and more robust Remote API, where the configuration of possible additional TER endpoints are not stored in the database anymore, the database table is removed.


Accessing tx_extensionmanager_domain_model_repository will result in a SQL error, as existing TYPO3 installations will drop this database table in the Database Compare View during upgrade.

Affected Installations

TYPO3 installations with third-party extensions accessing this database table, which is highly unlikely.

Also, TYPO3 installations depending on additional repositories rather than the official TYPO3 Extension Repository (TER) at, will not work anymore.


Additional Extension Repositories (remotes) have to be added in Configuration/Services.yaml using the extension.remote tag.
