It was originally written for Ubuntu although it is now part of the standard Debian operating system and other APT-based systems.The application was originally called Update Manager; it was announced in May 2012 that starting with Ubuntu 12.10 the name would change to Software Updater to better describe its functions.I noticed that I have lots of programs on my Debian 6.0.3 that need to be update. There is nothing as annoying as having a behavior of an important piece of software change in a subtle non-obvious way the day when you are rushing a deadline, just because the software was upgraded to its latest version overnight.

The transaction to remove the software deletes both the software and the dependencies.
Suppose "B" has been replaced on the filesystem, too. The question is: is it possible that "A" could find an incompatible version of "B" and crash or malfunction in some other way?
Why nobody update their systems by rebooting with a live CD or some similar procedure?
This functionality is included by default in the desktop version but needs to be added to the server version.
One of Debian's goals is to provide a consistent upgrade path and a secure upgrade process.
When the next version of Debian is released, a new, well tested combination of newer versions of software can be installed. Together with the "stable", or official, distribution, Debian maintains several other distributions: testing, unstable and experimental.
The main purpose is to allow volunteers to test new versions of packages and how they work together, in order to prepare the next stable version.
This number is larger just before a new major release.
