A recent bug report was filed because backup action starts bind9 daemon 
even when it is not explicitly enabled[1]. Could you please check if 
bind is running on your machine. Competing for the 53 port would explain 
some of your symptoms. You can ensure that bind9 daemon does not start 
by running:

systemctl mask named.service

Please confirm a fix with a few reboots (to ensure that dnsmasq is 
running as expected). Thanks for the detailed reporting and your 
patience with the issue.
