Piratebox 1.0.7: pacman -Syu broke ability to allocate IP addresses: "Obtaining IP address"

edit: added pastebin link for journal log


I used piratebox_rpi_1.0.7-1.img.zip as per [piratebox.cc]

TL;DR - installed latest Piratebox; updated OS software; Piratebox now broken

I followed the instructions to setup the Pi and confirmed that it worked, and I could connect to it: no problem.

As a sensible netizen I then decided to run a full system upgrade using pacman -Syu: this is a rather large update and took the release to Linux alarmpi 4.4.19-1-ARCH #1 Tue Aug 23 19:29:12 MDT 2016 armv6l GNU/Linux. I then rebooted and the piratebox came back up.

However, on my WiFi device (which has always worked with (piratebox) the WiFi connection is seen but it never connects: instead it just says "Obtaining IP address", then "IP Configuration Failure".

I suspected that a dnsmasq update might be the problem so I re-imaged the SD card with the original, working Piratebox img and rebooted. Then I edit /etc/pacman.conf and added "IgnorePkg = dnsmasq*" and reran pacman -Syu.

Here's a clue, but I'm not sure how to fix it:

Sep 06 10:33:10 alarmpi piratebox_alt[263]: Starting dnsmasq...
Sep 06 10:33:10 alarmpi piratebox_alt[263]: dnsmasq: failed to create listening socket for port 53: Address already in use
Sep 06 10:33:10 alarmpi dnsmasq[288]: failed to create listening socket for port 53: Address already in use
Sep 06 10:33:10 alarmpi dnsmasq[288]: FAILED to start up

Comments/hints please?
