The description contains a web URL in plain text. This is not allowed, please use the <url/> tag instead to share links.
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).
screenshot-download-error
Error while downloading screenshot from 'http://i.imgur.com/RTRgRdC.png': Unexpected status code: 429
This might be a temporary server issue, or the screenshot is no longer available.

asv-description-first-para-too-short
:10 - Supported Syncthing features:
The first `description/p` paragraph of this component might be too short (< 80 characters). Please consider starting with a longer paragraph to improve how the description looks like in software centers and to provide more detailed information on this component immediately in the first paragraph.
asv-nonstandard-gnome-extension
:31 - 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.
