I create a simeplestreams image mirror, but I only imported the xenial and bionic images. However, the index files of the mirror described not only the xenial/bionic images, but also, all other releases that were not imported.
Since MAAS gave me the option to select releases not in the mirror, I tried to import and:
1. MAAS didn't surface a UI error saying that the image was not available in the mirror: https://launchpadlibrarian.net/375181270/trusty-not-available.png
2. MAAS showed a nasty traceback while trying to download the image that wasn't available instead of catching the error aand showing a nice message:
