Nautilus : Extensions broken ?

[wyndon]

Describe the bug

It seems that many extensions are not working on Nautilus right now. In the right-click menu, I don't have a "Share" option, "Send to" is also missing, mat2 integration is not there either, nautilus-open-any-terminal same thing.

I started a Pop_OS! virtual machine, which was running GNOME 40, and I could see the "Share" and "Send to" options, I did not test the rest though.

Then, I started a Fedora virtual machine, which was running GNOME 42, and encountered the same problems as above (at least with Share and Send to), so I assume this is a problem with recent versions of GNOME/Nautilus. Opening for tracking.

Steps To Reproduce

Steps to reproduce the behavior:

1. Launch Nautilus and see if you have the "Share" and "Send To" options when you right-click on a file/folder.

Expected behavior

Extensions should work.

[con-f-use]

Same problem almost 8 months later. #126074 seems kinda related.

We rely on GNOME NixOS module setting NAUTILUS_EXTENSION_DIR environment variable for Nautilus to be find nautilus-python. That means nautilus-python needs to be installed via environment.systemPackages.

nautilus-python then needs its extensions to be available on XDG_DATA_DIRS path (in nautilus-python/extensions subdirectory). And it might fail if the extension depends on anything other than Nautilus and its dependencies.

If you do not use GNOME, you may need to ensure the path is linked to system when installed through environment.systemPackages with:

nixpkgs/nixos/modules/services/x11/desktop-managers/gnome.nix

Lines 528 to 530 in c06feee

	environment.pathsToLink = [
	"/share/nautilus-python/extensions"
	];

Also note that mat2 Nautilus extension does not support the current Nautilus version, see https://0xacab.org/jvoisin/mat2/-/issues/176.

perhaps this could be addressed now using #234615
