I need some help with the apt-get output. I started trying to install ethereal using apt-get and I don't know how I ended up downloading X and a lot of other stuff. I downloaded 78 mb and finally got a lot of dependencies problems that I can't fix. If somebody please can guide me a bit on how to fix this kind of issues I'll really appreciate it. This are the outputs:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.

I decided to start with x-window-system-core and tried to find the packages xserver-org in the debian search db but couldn't find it. I only found txt files. The same for most of them, I can't fix it because I don't even understand what's going on or what I did wrong. Thanks for your help!!!

by the way this is the ouptup when I try to install xfree86-common:
--(:root@elmotrina)-(/backup)--
--(1417:Sun,06 Aug 06:$)-- dpkg -i /home/elmo/xfree86-common_4.3.0.dfsg.1-14sarge1_all.deb
dpkg: regarding .../xfree86-common_4.3.0.dfsg.1-14sarge1_all.deb containing xfree86-common:
x11-common conflicts with xfree86-common (<< 6.8.0)
xfree86-common (version 4.3.0.dfsg.1-14sarge1) is to be installed.
dpkg: error processing /home/elmo/xfree86-common_4.3.0.dfsg.1-14sarge1_all.deb (--install):
conflicting packages - not installing xfree86-common
Errors were encountered while processing:
/home/elmo/xfree86-common_4.3.0.dfsg.1-14sarge1_all.deb

What is the problem, should I remove xfree86 and leave X or viceversa?

I hate you guys... I hate you very very much.

I have seen several threads in which people tried their best to help you. You don't follow instructions, you mix repositories wildly, You make bigger and bigger messes, and expect someone to somehow provide you with some kind of magic solution.

If you want to use Debian, you have to show the same kind of maturity that Debian has. Do a clean install of Etch. Use the official Etch repositories, and learn to function within those limitations. When you are knowledgeable enough to do that efficiently, you'll be able to ask questions coherently, and use the advice given in a constructive manner.

A political truism says that with freedom comes responsibility. In the free computing world, its very nature suggests that there are rules which must be followed if you are to expect success. Your interpretation of freedom seems to include wild shooting into the darkness and some unlikely expectation that everything will work out by itself.
