If I select packages and then "apply changes", if the downloadings fails, I have to select once more packages manually. It should be a "retry" option or at least the change list doesn't have to get empty. Reproducible: Always Steps to Reproduce: 1. select packages 2. apply change (without internet connection) 3. downloading fails 4. the change list is empty Actual Results: the change list is empty Expected Results: "downloading fails" but the list of selected package should be kept
