Bug#892456: gnome-software: no longer knows 'main' is Free Software (10_gnome-software.gschema.override needs updating) for 3.27

[Simon McVittie]

Package: gnome-software
Version: 3.27.90-1
Severity: normal

If you search gnome-software/experimental for (for example) openarena,
the Flatpak version from Flathub is listed as Free Software, but the
version in Debian main is listed as "Proprietary".

/usr/share/glib-2.0/schemas/10_gnome-software.gschema.override
is meant to configure GNOME Software to know that if a package is in Debian
'main' and does not have licensing information in its AppStream metadata,
then it must be Free Software under an unspecified license. However, the
GSettings keys that are overridden are no longer current for 3.27.x,
leading to warnings when the file is processed:

Processing triggers for libglib2.0-0:amd64 (2.55.2-2) ...
No such key 'official-sources' in schema 'org.gnome.software' as specified in override file '/usr/share/glib-2.0/schemas/10_gnome-software.gschema.override'; ignoring override for this key.
No such key 'free-sources' in schema 'org.gnome.software' as specified in override file '/usr/share/glib-2.0/schemas/10_gnome-software.gschema.override'; ignoring override for this key.
No such key 'free-sources-url' in schema 'org.gnome.software' as specified in override file '/usr/share/glib-2.0/schemas/10_gnome-software.gschema.override'; ignoring override for this key.

It looks as though these keys have been renamed to have "repos" instead of
"sources". Their contents might be in a different format now, I'm not sure.
