I don't think it's *-control-center. At the time, that was filed there by pitti, who correctly pointed out that something might need to depend on libnss-myhostname (from systemd) for a fallback to resolving hostname via just /etc/hostname (since /etc/hosts isn't changed). At this point though, it looks like this is no longer required.
Now, AFAICT the desktop correctly calls to systemd via dbus to ask for the change. I'll leave to you to make sure this is indeed the case (since you had commented on the bug previously, and I can't see any issues changing hostname as it is now, but maybe I'm not quite doing the same tests you were). unity-control-center is an obvious Won't Fix for Eoan or Disco, but I'll let the Desktop Team decide whether this needs to be fixed in other releases. Finally, this is still assigned to systemd, low priority, because hostnamed *doesn't* change /etc/hosts, and probably should (at the very least for consistency, to avoid keeping a reference to an old name for the system); but I didn't notice ill effects from not changing that file. sudo certainly doesn't hang here trying to resolve the new or old hostname. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1162475 Title: [hostnamed] Changing hostname doesn't update /etc/hosts Status in gnome-control-center package in Ubuntu: Triaged Status in systemd package in Ubuntu: Triaged Status in unity-control-center package in Ubuntu: Won't Fix Status in gnome-control-center source package in Xenial: New Status in systemd source package in Xenial: Triaged Status in unity-control-center source package in Xenial: New Status in gnome-control-center package in Debian: Fix Released Bug description: GUI --- 1a.

The hostname is updated instantly which can be verified by looking in /etc/hostname. However /etc/hosts/ is not updated. Command line ------------ hostnamectl set-hostname The hostnamed documentation at http://www.freedesktop.org/wiki/Software/systemd/hostnamed says "To properly handle name lookups with changing local hostnames without having to edit /etc/hosts for them we recommend using hostnamed in combination with nss-myhostname: http://0pointer.de/lennart/projects/nss-myhostname/ " Without /etc/hosts being handled correctly, the hostnamed integration is only half-working.
