Hints for transmission-gtk in main

transmission-gtk.desktop ⚙ amd64

asv-cid-desktopapp-is-not-rdns
transmission-gtk.metainfo.xml:7 - transmission-gtk.desktop
The component ID is not a reverse domain-name. Please update the ID to avoid future issues and be compatible with all AppStream implementations. You may also consider to update the name of the accompanying .desktop file to follow the latest version of the Desktop-Entry specification and use a rDNS name for it as well. In any case, do not forget to mention the new desktop-entry in a <launchable/> tag for this component to keep the application launchable from software centers and the .desktop file data associated with the metainfo data.

asv-id-tag-has-type
transmission-gtk.metainfo.xml:7 - transmission-gtk.desktop
The <id/> tag still contains a `type` property, probably from an old conversion to the recent metainfo format.
asv-developer-name-tag-deprecated
transmission-gtk.metainfo.xml:82 -
The toplevel `developer_name` element is deprecated. Please use the `name` element in a `developer` block instead.
