Ansible Install Failure on DO with adblock - dnsmasq fails

[jpetermans]

OS / Environment (where do you run Algo on)

Debian Stretch

Cloud Provider (where do you deploy Algo to)

DigitalOcean

Summary of the problem

Installation fails when deploying via ansible and using "dns" tag:

RUNNING HANDLER [dns_adblocking : restart dnsmasq] 
*********************************************
fatal: [138.68.49.66]: FAILED! => {"changed": false, "msg": "Unable to start service dnsmasq: 
Warning: dnsmasq.service changed on disk. Run 'systemctl daemon-reload' to reload units.
Job for dnsmasq.service failed because the control process exited with error code. 
See \"systemctl status dnsmasq.service\" and \"journalctl -xe\" for details.\n"}

Steps to reproduce the behavior

1. Installed with:

ansible-playbook deploy.yml -t digitalocean,vpn,cloud,ssh_tunneling,dns -e "do_access_token=<token> do_server_name=<name> do_region=<region>"

Install completes with no errors when installing via Ansible without "dns" tag completes with no errors using the ./algo script with DNS resolver selected.

On the Droplet the systemclt output gives

dnsmasq: failed to create listening socket for port 53: Address already in use

netstat:

dnscrypt-proxy tcp 172.16.0.1:53 LISTEN
dnscrypt-proxy tcp 127.0.2.1:53 LISTEN

Thanks!

Covered in #933
You can use a workaround for now - -e local_dns=true
