You guys all talk of aptitude as a CLI. But it is essentially a CUI
(Curses User Interface) supposed to give you diverse views of the status
of your packages and of what you are doing. I could never make any sense
of this CUI, although I know people who do. I've completely given up on
this and use only apt-get and synaptic. Synaptic is a GUI, very
straightforward to use. I think aptitude could be as easy but it has
been developped by geeks for their own use without care for the general
admin and without a sensible documentation.
