Take the 2-minute tour ×  I recently tried the new Ubuntu
release and when I wanted to change the cache setting of Ubuntu
update, I noticed that the Synaptic Package Manager was no
longer available.  Why? It was one of most useful applications
in Ubuntu in my opinion.  share|improve this question I do know
it can be download and installed. Please avoid this comment. –

try to advertise books and whatnot while I am just trying to
install a piece of software. –  chrisfs May 19 '12 at 17:21  3
Answers 3  up vote 6 down vote accepted  You can read a short
description about the reasons in the Ubuntu Wiki:
https://wiki.ubuntu.com/SoftwareCenter#Rationale   Early
versions of Ubuntu shipped many graphical utilities for
installing and removing software: Add/Remove Applications,
Synaptic Package Manager, Update Manager, Software Sources,
apturl, GDebi, and Computer Janitor. This redundancy increased
the amount of interface people had to learn, wasted space
