Debian recently added a website for screenshots:
I think it would be great if PackageKit could have some way to view screenshots from the distro being used. When there is no screenshot available, it should encourage users to provide new screenshots.
We moved the upstream bugtracker to GitHub a long time ago. If this issue still affects you please re-create the issue here: https://github.com/hughsie/PackageKit/issues
Sorry for the impersonal message, and fingers crossed your issue no longer happens. Thanks.
