Erro: Abrindo o cache

[Lazzarinni]

Tentei instalar um msn pro ubuntu e deu erro em tudo aqui, nao consigo mais instalar nem desinstalar nada e nem abrir a central de programas
tem um erro escrito assim:

"Um erro ocorreu, por favor,use o Gerenciador de Pacotes a partir do menu com clique direito ou apt-get em um terminal para ver o que está errado.
A mensagem do erro foi: 'Erro: abrindo o cache (E:encountered a section with MergeList /var/lib/apt/lists/www.getautomatix.com_apt_dists_feisty_main_binary-i386_packages, E:The package lists or status file could not be parsed or opened.)'. Isso geralmente significa que os pacotes instalados possuem dependencias nao resolvidas"

Quando uso o comando sudo gedit /etc/apt/sources.list

aparece uma caixa com a seguinte informação:

Se alguém souber como resolver por favor... ajudem

obs: se alguem souber como apaga todos os programas sem usar o comando apt-get sem afetar o OS pode resolver meu problema, obrigado.

Copie e cole no terminal:

Código: [Selecionar]

sudo rm /var/lib/apt/lists/* ; sudo rm /var/lib/apt/lists/partial/* ; sudo apt-get -f install ; sudo apt-get clean ; sudo apt-get update

Ola agregando ao que o Ioca reportou, existe o automatix ainda??? Eu acho que nao....esse programa caiu em desuso.

deb http://www.getautomatix.com/apt feisty main
deb http://www.getautomatix.com/apt feisty main

Pode remover essas duas ultimas linhas.

O Feisty é o ubuntu 7.04...
