Bug#1002840: Screenshots in gnome-software still broken for all debian packages in 2026

[Sean Campbell]

This is still happening on a fresh install of Debian 13 with KDE - so it's
not gnome specific.  All tested thumbnails return 404 not found.  I'm not
sure how you aren't able to reproduce this issue.  How can I help?
