Package: neochat Version: 24.08.1-4 NeoChat is missing in modern GUI software centers such as GNOME Software or KDE Discover because it has no AppStream metadata generated for some reason: https://appstream.debian.org/sid/main/metainfo/neochat.html Both the desktop and appdata files seem to be correct and the desktop icon is also fine so I am not sure where the problem is.
