  This is essentially a confirmation of https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=825380

  I had the combination of smb and autofs working in Ubuntu 16.04 and
  then recently upgraded to 18.04.  I hadn't checked my back-up logs
  that used autofs+smb for a while but today noticed that autofs claimed
  that it could not resolve my Win10 hostname (the remote backup
  endpoint).  I found the above Debian bug report and can confirm that
  the issue is present in 18.04.

  Steps to reproduce:
  # ping abcomputer
  ping: abcomputer : System error

  # nmblookup abcomputer
  192.168.1.8 abcomputer<00>
  192.168.5.1 abcomputer<00>

  Note the 192.168.5.1 IP is a Virtualbox host-only interface on the
  Win10 machine.  I then remove the host-only interface from the Win10
  computer

  # nmblookup abcomputer
  192.168.1.8 abcomputer<00>

  # ping hyperion
  PING abcomputer (192.168.1.8) 56(84) bytes of data.
  64 bytes from 192.168.1.8 (192.168.1.8): icmp_seq=1 ttl=128 time=0.533 ms
