Error running dotdocker on Ubuntu 18.04

[outkaj]

Describe the bug dotdocker fails with resolution error during configuration on an Ubuntu 18.04 VM

To Reproduce

make sure docker-proxy is stopped by running docker-proxy stop
sudo systemctl stop systemd-resolved (note - if I restart this before running dotdocker I get the same error)
add 8.8.8.8 to /etc/resolv.conf
sudo npm install -g dotdocker
kill any processes on ports 53, 80, 443
sudo dotdocker start

output:

sudo: unable to resolve host ip-*machine-ip*

Expected behavior I would expect dotdocker setup to succeed.

Screenshots N/A (see log output above)

Additional context aj-may mentioned making sure no other process was running on port 53 and making sure Docker has permissions to listen on that port. I've checked the first but not the second - would the best way to do the latter just be to run sudo /usr/bin/docker daemon -H tcp://0.0.0.0:53 -H unix:///var/run/docker.sock?

I've gotten past that error and on to a later one:
