Error messages should mention affected repo

I currently have an issue where I am not sure what repo causing my issues. When downloading/updating the repo I only get a strange error message.

Sometimes I also saw I get the same error message multiple times (below, line by line). In any case, I do not know to which repo it belongs. So to increase the UX (and the possibility to report an error), the error toast should mention the repo, which is causing the specific issue.
