Após uma atualização para o Oneiric, tive alguns problemas com o gerenciador de pacotes (ele queria remover metade do meu sistema, incluindo pacotes libc6, zlib1g, etc.). Durante a luta com o fitness notei que alguns pacotes possuem meta-informação que afirma que eles conflitam consigo mesmos. Exemplos:
% aptitude show libc-bin
Package: libc-bin
Essential: yes
New: yes
State: installed
Automatically installed: no
Version: 2.13-20ubuntu5
Priority: required
Section: libs
Maintainer: Ubuntu Developers <[email protected]>

Conflicts: libc-bin
Breaks: libc0.1 (< 2.10), libc0.1 (< 2.10), libc0.3 (< 2.10), libc0.3 (< 2.10), libc6 (< 2.10), libc6 (< 2.10), libc6.1 (< 2.10), libc6.1 (< 2.10)
Replaces: libc0.1, libc0.1, libc0.3, libc0.3, libc6, libc6, libc6.1, libc6.1

O mesmo recurso "conflita consigo mesmo".
Eu resolvi meus problemas com o gerenciador de pacotes agora, mas a questão ainda me incomoda: o que significa quando um pacote entra em conflito? Para que isso é usado?
