quassel binary package in Ubuntu Lunar amd64

 Quassel is a modern, cross-platform, distributed IRC client, meaning that
 one or more clients can attach to and detach from the central core. It's
 much like the popular combination of screen and a text-based IRC client
 such as WeeChat or irssi, but graphical.
 .
 This package provides the monolithic client. It contains both core and
 client and can be used like a traditional IRC client, without requiring an
 external core.
