It appears that the appstream project no longer supports `translatable=no` properties, and gettext extract the `translatable=no` marked strings as translatable. I opened an issue to inform about the situation, but `translatable=no` properties are not accepted by developers. You can find the issue here: https://github.com/ximion/appstream/issues/623 Please test your script or string extraction process before merging this PR. > In MetaInfo files, each individual paragraph of a description > (or enumerated entry) is translated individually, however, > you can only exclude the complete block from being translated > by adding `translate="no"` to the description element.
