Running updatedb fails with UnknownExtensionException error
Drupal can't find the module when it's scanning the codebase. You'll have to debug to figure out why. Run drush eval 'print_r(array_map(function ($ext) { return $ext-&gt;subpath; }, \Drupal::service("extension.list.module")-&gt;getList()));' to have Drupal dump what modules it can see and try see why it can't find the install location location (file permissions?).
