gnats binary package in Ubuntu Trusty arm64

 GNATS is a bug-tracking tool designed for use at a central "Support
 Site". Users who experience problems use electronic mail to
 communicate these problems to "maintainers" at that Support Site.
 .
 GNATS offers many of the same features offered by more generalized
 databases, including editing, querying, and basic reporting. You can
 access the submitting, editing, and querying functions of GNATS
 through provided utilities or from within GNU Emacs.
 .
 The "gnats" package has the full installation for the central database
 server. For client systems, use the "gnats-user" package which has just
 the user tools.
