Title:
  DNS setting is not reflected in netplan yaml file when domain name
  isempty string

Status in netcfg package in Ubuntu:
  New

Bug description:
  Package: netcfg
  Version: 1.142
  Severity: normal

  Dear Maintainer,

  When we install ubuntu server and set DNS addresses (ex. 8.8.8.8), the
  event that the DNS setting is not reflected in netplan yaml file
  (/etc/netplan/*.yaml) may occur.

  We finded that the reason is related to the source code of the network
  package 'netcfg'.

  In the function 'nc_wi_netplan_write_nameservers' of write_interface.c
  of netcfg-1.142ubuntu5(netcfg package source code directory), the
  nameservers are not written in the netplan yaml file if domain name is
  empty string.

  We hope that the nameservers are written even if domain name is empty
  string.
