aptitude-dbg 0.7.4-2ubuntu2 (armhf binary) in ubuntu xenial

 aptitude is a package manager with a number of useful features,
 including: a mutt-like syntax for matching packages in a flexible
 manner, dselect-like persistence of user actions, the ability to
 retrieve and display the Debian changelog of most packages, and a
 command-line mode similar to that of apt-get.
 .
 This package contains the debugging symbols for aptitude. You only
 need these if you want to generate debugging backtraces of aptitude;
 if you do, you probably also want the debug package for the cwidget
 library.
