Settings schema 'org.gnome.shell.overrides' is not installed

I recently upgraded to Fedora 38 and Gnome 44, and one of my installed applications give this error message here:

1
Settings schema 'org.gnome.shell.overrides' is not installed

And sure enough, that schema does not exist:

1
2
[akaris@linux schema]$ gsettings list-schemas | grep org.gnome.shell.overrides
[akaris@linux schema]$ 

I ran into this with a 3rd party application today, and it seems like I am not the only one: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-tiling-assistant/+bug/2008139

I can't fix the 3rd party application that I'm using, but I found a workaround for my case. I'm pretty sure that this workaround isn't complete for all cases, but it did the job for me.

    data: Remove unused overrides schema

    The old custom overrides mechanism was superseded by
    session-specific defaults back in 2018. By now any
    potential consumers (like gnome-tweaks) should have
    adjusted, so time to remove it.

Now, I do have a feeling that this commit might be related to this too, but I don't need it for my workaround:

    tools: Drop gnome-shell-overrides-migration.sh

    The tool was added in 2018 to migrate to per-desktop overrides from the
    old overrides system.

    5 years later, everyone who’s going to migrate probably has migrated, so
    we can delete the script and remove a process running on every login.

EOF
sudo cp org.gnome.shell.overrides.gschema.xml /usr/share/glib-2.0/schemas/

Now, recompile the schemas:

1
2
cd /usr/share/glib-2.0/schemas/
sudo glib-compile-schemas .

And verify:

1
2
[akaris@linux schema]$ gsettings list-schemas | grep org.gnome.shell.overrides
org.gnome.shell.overrides

That's it, this fixed my crashing 3rd party app for me.
