Hints for +extra-metainfo in main

firefox.desktop ⚙ amd64

Errors

  • gui-app-without-icon
    The component is a GUI application (application which has a .desktop file for the XDG menu and Type=Application), but we could not find a matching icon for this application.

Warnings

  • asv-cid-desktopapp-is-not-rdns
    :4 - firefox.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-circular-component-relation
    :49 -
    This component extends, provides, requires or recommends itself, which is certainly not intended and may confuse users or machines dealing with this metadata.
  • asv-screenshot-no-media
    :52 -
    A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.
  • asv-screenshot-no-media
    :53 -
    A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.
  • asv-screenshot-no-media
    :54 -
    A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.
  • asv-invalid-iso8601-date
    :57 - __DATE__
    The AppStream specification requires a complete, ISO 8601 date string with at least day-granularity to denote dates. Please ensure the date string is valid.
  • missing-launchable-desktop-file
    The MetaInfo file references a .desktop file with ID 'firefox.desktop' in its launchable tag, but the file was not found in the same source tree. In order to be able to launch the software once it was installed, please place the MetaInfo file and its .desktop files in the same package.
  • translations-not-found
    Unable to add languages information, even though a translation tag was present in the MetaInfo file. Please check that its value is set correctly, and all locale files are placed in the right directories (e.g. /usr/share/locale/*/LC_MESSAGES/ for Gettext .mo files).

Hints

  • asv-nonstandard-gnome-extension
    :38 - kudos
    This tag is a GNOME-specific extension to AppStream and not part of the official specification. Do not expect it to work in all implementations and in all software centers.
  • asv-desktop-app-launchable-omitted
    -
    This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that this application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
  • asv-content-rating-missing
    -
    This component has no `content_rating` tag to provide age rating information. You can generate the tag data online by answering a few questions at https://hughsie.github.io/oars/
