Binary package “knews” in ubuntu bionic
Graphical threaded news reader
Knews is an X11 based thread-oriented news reader. It is capable of
representing threads as a graphical tree, represents quotations with
different colors and much more.
.
Also included here is knewsd, a tiny NNTP daemon which can read news
from a spool directory or even from a mail folder hierarchy, for use
when you don't have a real server available. There is no guarantee
that it will work with any client other than knews, so it is not
packaged separately.
