Problema Central de Programas não abre

[Mettalicawil]

Bom dia amigos, estou iniciando no Ubuntu agora e estou fascinado com isso tudo!
Encontrei essa comunidade e já me deparei com uma ótima qualidade de dicas e tutorias.

Bom pesquisei e não encontrei nada parecido,
Primeiramente estava com um problema com a Central de Programas Ubuntu que não abria,
pesquisei e encontrei esse seguinte comando usando o Terminal

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

mas quando eu abro o Terminal que colo o comando aparece

sudo rm /var/lib/apt/lists/* ; sudo rm /var/lib/apt/lists/partial/* ; sudo apt-get clean ; sudo apt-get -f install ; sudo apt-get update
rm: remover arquivo comum "/var/lib/apt/lists/br.archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages" protegido contra escrita?

digito sim e aparece permissão negada, alguém pode me ajudar referente a isso ?
minha versão Ubuntu 11.04
agradeço pelas respostas

O comando mencionado acima apenas lhe pedirá sua senha root, portanto é estranho.

mas quando eu abro o Terminal que colo o comando aparece

sudo rm /var/lib/apt/lists/* ; sudo rm /var/lib/apt/lists/partial/* ; sudo apt-get clean ; sudo apt-get -f install ; sudo apt-get update
rm: remover arquivo comum "/var/lib/apt/lists/br.archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages" protegido contra escrita?

digito sim e aparece permissão negada, alguém pode me ajudar referente a isso ?

Não entendi, você digita sim??

Repita o comando no terminal copie e cole lá>de enter>digite sua senha>enter novamente e aguarde o resultado

Quando completar tudo, copie desde o primeiro comando até em baixo e cole o resultado aqui

Você está vendo isso que grifei em vermelho?

Foi alguma coisa que você adicionou e não faz parte do ubuntu

Faça o seguinte de novo vá em synaptic>configuração>repositórios>outros aplicativos

Desmarque tudo que estiver relacionado com http://extras.ubuntu.com/ubuntu natty main

Recarregue

[Mettalicawil]

Agora surgiu outro problema
reinicei já diversas vezes, entro no Synaptic > configurações> repositórios e não entra 

[Paulo Correa]

Vamos por partes, certo?!

O que você instalou ou tentou acrescentar nos repositórios?

Antes de responder

De novo no terminal

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

Copie e cole a saida aqui por favor.
