Hello, After much time spent trying to fix/update python-nautilus failing on core-updates-frozen, I realized this is not actually a package needed by anything in Guix. Packages actually wanted nautilus-python for integration with the nautilus file manager, not this one: https://gitlab.gnome.org/GNOME/nautilus-python Since the package is unused by other packages then, and dates from 2016 (perhaps inactive), I've gone ahead and removed it. This should fix (or help fix) the related builds failing on core-updates-frozen. I've tested that one of the packages that have this as an input, syncthing-gtk, builds and runs without it. I have not tried the others but have checked upstream listed nautilus-python as what they wanted which is a different package. I have a WIP patch that added some python packages that were needed to update python-nautilus, which I'll send as a bug report in case it is helpful to someone later. Thanks, John
