I confirm that every second
$ systemctl restart dnsmasq
hangs
Also I confirm that removing squid resolved the situation.
I found that it does this:
1. /bin/sh /etc/init.d/dnsmasq systemd-stop-resolvconf
2. /bin/sh /etc/init.d/dnsmasq systemd-start-resolvconf
Both will call hooks like:
0 0 11642 11634 20 0 4364 660 wait S ? 0:00 \_
run-parts --arg=-a --arg=lo.dnsmasq /etc/resolvconf/update.d
0 0 11659 11642 20 0 4364 664 wait S ? 0:00 \_
run-parts /etc/resolvconf/update-libc.d
0 0 11672 11659 20 0 4504 704 wait S ? 0:00
\_ /bin/sh /etc/resolvconf/update-libc.d/squid
0 0 11673 11672 20 0 4504 1648 wait S ? 0:00
\_ /bin/sh /usr/sbin/invoke-rc.d squid reload
4 0 11691 11673 20 0 24888 1388 poll_s S ? 0:00
\_ systemctl reload squid.service
This is what actually times out - the squid hook.
The "systemctl reload squid.service" call seems to take too long every
second time?!
A single "systemctl reload squid.service" for these seems to take ~100 seconds
for me.
OTOH a direct call to it is fast every time.
This needs to be debugged in detail, but seems well reproducible.

Bug description:
Setup to reproduce:
Ubuntu Xenial amd64 net install iso from
http://archive.ubuntu.com/ubuntu/dists/xenial/main/installer-
amd64/current/images/netboot/mini.iso
Install system with mostly defaults + LVM + OpenSSH server
Note that this bug applies to both DHCP and static IP+DNS network
configurations
Once server rebooted and is available, log in and install dnsmasq + squid:
apt-get update && apt-get install squid dnsmasq
output of this can be found at https://pastebin.com/9Atuipju
journalctl -xe output at https://pastebin.com/uLhfM4jN
Furthermore at this point I can run alternating errors
root@ubuntu-min:~# date ; service dnsmasq start ; date
Wed Apr 4 09:18:07 CEST 2018
Wed Apr 4 09:18:07 CEST 2018
root@ubuntu-min:~# date ; service dnsmasq stop ; date
Wed Apr 4 09:18:39 CEST 2018
Wed Apr 4 09:18:39 CEST 2018
root@ubuntu-min:~# date ; service dnsmasq start ; date
Wed Apr 4 09:19:10 CEST 2018
Job for dnsmasq.service failed because a timeout was exceeded. See "systemctl
status dnsmasq.service" and "journalctl -xe" for details.
Wed Apr 4 09:20:40 CEST 2018
root@ubuntu-min:~# date ; service dnsmasq start ; date
Wed Apr 4 09:42:57 CEST 2018
Wed Apr 4 09:42:57 CEST 2018
root@ubuntu-min:~# date ; service dnsmasq stop ; date

and so on... Each and every 1 out of 2 stop/start cycle fails in 1m30s
timeout
Complete journalctl -xe output attached
