Errors

icon-not-found
The icon 'battery-full' 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.

Found invalid tag. Non-standard tags should be prefixed with `x-`. AppStream also provides the <custom/> tag to add arbitrary custom data to metainfo files. This tag is read by AppStream libraries and may be useful instead of defining new custom toplevel or `x-`-prefixed tags if you just want to add custom data to a metainfo file.
