AppStream Report for PureOS - Issues for angband-data in landing/main

Errors

icon-not-found
The icon 'angband' was not found in the archive. This issue can have multiple reasons:
- The icon is not present in the archive.
- The icon is in a wrong directory.
- The icon is not available in a suitable size (at least 64x64px)
- On Debian and Ubuntu, the icon is a symlink. The generator cannot read symlinks on these distributions - make the icon a real file.
To make the icon easier to find, place it in /usr/share/icons/hicolor/<size>/apps and ensure the Icon= value of the .desktop file is set correctly.

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.
