If I try it at the terminal, this is what I get

I've tried an apt-get update and nothing changes.

Any help?

LANG=C apt-get ... will print the message in the default language (English, technically C is for POSIX). This makes it easier to discuss the problem in an international forum. –  Jan Aug 19 '11 at 19:00
    
Your terminal output is not in English, which might make it difficult for lots of people to answer your question. You should consider temporarily changing languages and reposting the output. Or at least translating the error messages. –  Kris Harper Aug 19 '11 at 19:01
    
@Souljacker Welcome! i have added the google translation if you think that is the correct translation you may remove the Portuguese ;) –  Achu Aug 19 '11 at 19:04
    
I was just thinking about the language issue, so I swiched Ubuntu to English and also changed it's default repository to the original instead of the one in Brazil. And that was it. Now removal is working ;) I've seem plenty of Brazilian people with the very same problem while searching for a solution. Maybe this will help then :) –  Souljacker Aug 19 '11 at 19:16
    
askubuntu.com/questions/29600/… Try updating your server and then try the command again –  Allan Aug 19 '11 at 19:31

I did a little searching and it seems the problem is with the Brazilian repository
mirror (http://br.archive.ubuntu.com). Go to Software Center ➜ Edit ➜ Software Sources... and change the download server.

Edit: apt is also part of the problem, but DoR is right, the main problem is with connection to Brazilian mirror, so change of mirror will solve this problem as well.


There are some packages depending on libavcodec52 (in my system I've found mplayer, but also vlc and maybe other multimedia applications) and it seems apt can't resolve this conflict.

You can try to remove those applications first (I see VLC in the apt output) and then remove libavcodecs52 or install aptitude which has better system for resolving conflicts.

aptitude has similar syntax, so you can remove packages using

sudo aptitude remove package

Tried and worked for me - apt is "stuck" but aptitude offers removing of mplayer and that solves the problem (libavcodecs52 is removed properly without installing anything new).
