Comment 17 for bug 1439109

Firstly note that this is more like bug #1432173.
Adding this comment here since that is a duplicate of this one

I get :

$ systemctl status -l ifup-wait-all-auto.service

$ sudo vi /etc/resolv.conf

I tried what looked like solutions offered here:
1.
$ sudo update-rc.d networking remove
$ sudo update-rc.d networking defaults

[I am assuming that r.cd is a misspelling of rc.d]

No change

2. Reinstalled ifupdown
I believe I used to see two segfaults. Now I see one

Ubuntu wily
ifupdown 0.7.54ubuntu1
systemd 225-1ubuntu9

$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto enp7s0
iface enp7s0 inet dhcp
