Hi,

I am trying to setup pharos cluster on ubuntu 18.04 a, getting the following error 

    # nameserver config

Does it have something to do with IPv6/6 ?

No, it seems to be a bug in Pharos.

For a quick fix, remove the first comment line from /etc/resolv.conf

The problem is the unanchored /nameserver (.*)/ in https://github.com/kontena/pharos-cluster/blob/master/lib/pharos/phases/gather_facts.rb#L105
