If the appdata provides a screenshot URL, Discover still gets it from screenshots.debian. The debian one should only be used as a fallback. Reproducible: Always Steps to Reproduce: 1.Search for 'dolphin' Actual Results: 2. The screenshot from debian is used. Expected Results: 3. Screenshot URL from the dolphin appdata should be used (http://kde.org/images/screenshots/dolphin.png), as gnome-software does.
That must be an issue downstream somewhere: $ appstreamcli search dolphin --details Identifier: org.kde.dolphin.desktop [desktop] Name: Dolphin Summary: File Manager Package: dolphin Homepage: http://dolphin.kde.org/ Icon: dolphin_system-file-manager.png Description: Dolphin is a lightweight file manager.
