@mathieuepitech Ah, I didn't realize you were on a older Cloudron version. Indeed, du.py is now gone.
@zjuhasz1 Right, this is also fixed. The packages were installed because we use apt without --no-install-recommends. You can remove those gnome packages by hand for now if it bothers you but it doesn't run any daemons, so it's mostly harmless.
This is fixed in the next release. Thanks for reporting!
