metainfo-no-summary
Component does not contain a short summary. Ensure that the components metainfo file has a summary tag, or that its .desktop file has a Comment= field set. Especially applications by KDE often use the GenericName field for a short summary, instead of the Comment field (which is not its intended use case).
More information can be found in the Desktop Entry specification.

description-from-package
This component gets its description from the package it is located in.
This has several disadvantages, like missing localization, possibly too short descriptions, too technical descriptions for users of software centers, etc.
Please consider writing a metainfo file for this component. In the near future, components without metainfo file might be dropped from the metadata. You can consult the XML quickstart guide for more information on how to write a metainfo file.

missing-desktop-file
Found an AppStream upstream XML file, but the associated .desktop file is missing. This often happens when the .desktop file is renamed, but the <id/> tag of the AppStream metainfo file is not adapted as well, or if the metainfo file is located in a different package than the .desktop file.
Please fix the packaging or work with upstream to resolve this issue.
