Code

public function submitForm(array &$form, FormStateInterface $form_state) {
  // Remove the key value store entry.
  $account = $this->currentUser()
    ->id();
  $this->keyValueExpirable
    ->delete($account);
  if (!empty($this->modules['install'])) {
    // Don't catch the exception that this can throw for missing dependencies:
    // the form doesn't allow modules with unmet dependencies, so the only way
    // this can happen is if the filesystem changed between form display and
    // submit, in which case the user has bigger problems.
    try {
      // Install the given modules.
      $this->moduleInstaller
        ->install(array_keys($this->modules['install']));
