upgrade:
  
  Upgrading should only be done from one release to the next release
  (e.g. Ubuntu 16.04 to Ubuntu 16.10) or from one *LTS* release to
  the next (e.g. Ubuntu 16.04 LTS to Ubuntu 18.04 LTS). If you
  wish to 'skip' a version, you can back up your data and do a
  fresh installation, or progressively upgrade to each successive
  version. For example, to upgrade from Ubuntu 16.10 to Ubuntu 17.10,
  first upgrade to 17.04, then upgrade 17.04 to 17.10.
