Very true. However, Ubuntu is based on Debian which has the excellent Apt tool for handling all of the dependency issues for you, and it is native to Ubuntu, unlike autopackage. Plus Apt is quite simple to use:
From the command line, just issue the command:
sudo apt-get install foobar
is a name of some software package that you wish to install.
Don't know what the software package is called? No problem! Just issue the command:
sudo apt-cache search foobar
where again foobar is the name of some software package or some term relating to it that you're looking for.
Want to update your system with the lastest security patches? Issue the command:
sudo apt-get update && sudo apt-get upgrade
If the command line isn't your thing and you want a nice graphical interface then there are several available for apt. The one that I like best is called Synaptic. You can install/search for/upgrade packages all without ever having to even touch the CLI.
If you're looking for a place to help you get going with Ubuntu, I'd highly recommend the unofficial Ubuntu Guide for 5.10:
It covers quite a few of the questions that most people new to Ubuntu want answered and it does so in a fairly simple step-by-step approach.
Hope that helps!
Oh, and by the way, welcome to the Linux community!
