Earlier today I started to upgrade to 13.10 only to return much much later and notice that the update manager was still running. It seems to be frozen and I am reluctant to hit ctrl+C. I can't launch nautilus using the icon on the launcher. When I try to run it via the terminal, this is what happens: $ nautilus Could not register the application: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gtk.Actions' on object at path /org/gnome/Nautilus My printers aren't showing up when I attempt to print. I don't know whether these a symptoms of the same problem. Should I let the update manage continue to run, or should I shut it down? Here are the processes running if it is any help: $ ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.2 5920 4072 ? Ss Oct18 0:02 /sbin/init root 2 0.0 0.0 0 0 ?
