We automatically package all extensions from [https://extensions.gnome.org/](https://extensions.gnome.org/) but the the official GNOME extensions packaged in `gnome-shell-extensions` package are bit of a special case since they are a part of a [single project](https://gitlab.gnome.org/GNOME/gnome-shell-extensions) and are packaged together as such. We should either remove them from the list of automatically packaged extensions or make the attributes point to `gnome.gnome-shell-extensions`.

If you have both packages installed, there is probably a file conflict so Nix chooses the file it ¿sees first?

Since it is automatically packaged, it is indeed packaged incorrectly. The system is not smart enough and will require a human intervention. @piegames I wonder how hard it would be to scan extensions for typelib includes and resolve that automatically. Then again there are external dependencies on programs installed to `PATH`, which would be much harder to catch.

GNOME Shell extensions installed through Nix should work. If they do not please open a bug in Nixpkgs issue tracker.
