Public bug reported:
iproute2 fix in -proposed
(https://launchpad.net/ubuntu/+source/iproute2/4.18.0-1ubuntu3) has
showed regressions in chrony autopkgtest (object of this bug report).
>From autopkgtest output:

It is likely that the stdout from md5sum coming out of the dhclient
command caused the "regression".
I have reproduced the issue by hand doing:
$ apt-get install isc-dhcp-server
$ modprobe dummy
$ ip link add name dummy0 type dummy
$ ip address add 192.168.1.1/24 dev dummy0
$ ip link set dev dummy0 up
cat <<EOF > /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
authorative;
subnet 192.168.1.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option ntp-servers 192.168.1.50;
range 192.168.1.42 192.168.1.100;
}
EOF
$ sed -i 's/INTERFACESv4=""/INTERFACESv4="dummy0"/' /etc/default/isc-
dhcp-server
and
$ systemctl restart isc-dhcp-server
$ dhclient dummy0 <- problem happens here
It could be a "isc-dhcp-client"problem, but I'll keep this bug linked to
another bug if that is the case.
