[Bug 1775219] Re: incorrectly reports package as unsupported if apt cache is empty

[Robert C Jennings]

** Description changed:

  Cloud images ship with empty /var/lib/apt/lists/ to save on size.
  Running 'ubuntu-bug <supported_package>' will erroneously report that
  the package is unsupported:
  
-   $ ubuntu-bug coreutils

  A simpler recreate is:

  True
  
  Desired result:
  
  The message should instruct the user to run 'apt update' as root if they
  think this is in error.   That would improve usability and avoid false
  reports about apport incorrectly flagging a package as unsupported.
  
  Additionally, if the user is root (and optionally if the set of package
  candidates only contains a 'now' component) self._cache.update();
  self._cache.open() could be called to download lists.
