Central de Programas do Ubuntu não abre

[markuscorreia]

Oi pessoal, sou novo aqui no fórum e na utilização do Ubuntu.
Instalei o Ubuntu 10.10, mas não consigo instalar nenhum programa nele.
Quando tento abrir a central de programas do Ubuntu, ela fica carregando e simplesmente não abre!
Já tentei instalar programas de várias formas, mas não consigo!
Tentei também abrir através do terminal mas apresenta o seguinte erro, alguem sabe informar do que se trata?

Usu@D6702:~$ sudo software-center

ôpa blz, é que eu estou começando agora literalmente, então algumas coisas ainda não entendo muito bem, valeu abriu meus olhos..rs
Mas, continuo sem conseguir instalar programas, eu clico lá no programa que quero instalar, clico em usar a fonte que aparece, ele roda por alguns momentos e para sem resposta alguma. Tentei pelo terminal mas aparece a seguinte mensagem;

Usu@D6702:~$ sudo apt-get install amsn
Lendo listas de pacotes... Pronto
Construindo árvore de dependências       
Lendo informação de estado... Pronto
E: Impossível encontrar o pacote amsn
Usu@D6702:~$

Eu acesso a internet através de um proxy, será que tem algo haver?

Obrigado!

Tenta atualizar a lista assim:

Código: [Selecionar]

sudo apt-get update
Se continuar posta o conteúdo do arquivo /etc/apt/sources.list

T+.

Bom dia Ronaldo, eu já tinha tentado este método, mas tentei novamente e continua o problema.
Em todas as linhas informa o seguinte:
