Many years ago I wrote How to display available updates blog post which mainly related to Debian Wheezy. Today I want to extend it by a neat console friendly utility available in Debian Jessie since the milestone apt release thanks to Michael Vogt.
List available updates using apt
command.
$ apt list --upgradable
Listing...
