Application languages not available in Flathub appstream.xml

[fedelibre]

There’s something wrong with the appstream.xml generated by Flathub. An app I maintain (Frescobaldi) appears as translated in my language (Italian) in GNOME Software if I choose the RPM source, but I see the message “This application will appear in US English” if I choose Flathub source:

I know that my local appstream.xml contains the following strings for Frescobaldi:

<languages>
  <lang percentage="100">en_US</lang>
</languages>

despite the fact that the metainfo.xml file has the right lang tags (check with the command flatpak run --command=cat org.frescobaldi.Frescobaldi /app/share/metainfo/org.frescobaldi.Frescobaldi.metainfo.xml).

I should have a look at the logs of the generation of appstream.xml file for Flathub. Where can I find it?

It’s because the metainfo has <translation type="gettext">frescobaldi</translation> but

ls /app/share/locale/
en_US  fi

That’s where the translation mo files are supposed to live. MetaInfo guidelines | Flathub Documentation

[fedelibre]

it’s well documented

Frescobaldi places the mo files inside its python installation. I’ll add a step in the manifest to copy the files in the proper location.

Can you please tell me what I’m doing wrong here?

EDIT: problem solved in this discussion.

When I compare the stable branch with the test branch of that PR build I see some changes, but not exactly what I was expecting.
