ifupdown does the right thing here. When you ask it to tear down the network, it'll do so and only keep the loopback device, it'll then emit deconfiguring-networking.
Some jobs stop on deconfiguring-networking like dbus, which is a core dependency of the rest of the desktop which unsurprisingly causes everything to die. ** Changed in: ifupdown (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098941 Title: "sudo service networking stop" causes the GUI to crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1098941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
