Sentry Crash Report:

Description Nate Graham 2021-10-22 15:59:31 UTC

It is possible for Discover to end up in a situation where it has no app backends present, or no valid repos for any app backends. (for example if the distro ships with only the Flatpak backend, but neglects to add any flatpak repos).

In such a circumstance discover announces that no apps were found and advocates checking the network connection, which is a red herring in this case. It should be intelligent enough to distinguish between "I can't find apps because I can't connect to the internet" and "I can't find apps because there are no valid app repos configured"

Improve error messages when the default source is not behaving

Addresses the weird error message we always get when the default backend
isn't working as expected.
Allows the backend to explain why instead of wildly guessing from the
frontend.
