Erro ao atualizar o Ubuntu 12.04

[Gui1204]

Olá!

Uso o Ubuntu 12.04 desde o final de julho e nunca tinha usado Linux antes. Ou seja, sou novato.
Percebi que ao longo do último mês, ao tentar atualizá-lo, aparece a mensagem "As informações dos pacotes foram atualizadas há X dias.".
Assim, creio que o sistema esteja desatualizado de alguma forma, pois algumas poucas atualizações ocorrem e até pedem a reinicialização, mas na mensagem só aumenta o número de dias (33).
Visitei alguns fóruns e encontrei casos parecidos, mas sem soluções.
Usando o menu "Software atualizado > Gerenciador de atualizações > Verificar" surge a janela "Atualizando cache" com várias linhas (Pacote..., Traduções..., Descrição..., Estruturas... etc.) e seus resultados (baixado, ocioso ou falhou). Entretanto, numa nova atualização, as mesmas mensagens se repetem. Parece que o sistema não se atualiza.
Na configuração "Canais de software", já usei na aba "Aplicativos Ubuntu": Servidor principal, Servidor-Brasil e http://mirror.unesp.br/ubuntu. Sem sucesso.
A configuração da aba "Outro software" está com todos “Código Fonte” desmarcados.
A aba "Atualizações" está com as 4 opções marcadas + diariamente, imediatamente e versão LTS.
Já usei os comandos "sudo apt-get update" e "sudo apt-get upgrade" no Terminal. Também sem sucesso.
Tudo parece funcionar bem no PC e estou fazendo esse contato a partir dele.
Sem saber o que fazer a partir de agora, recorro a esse fórum em busca de ajuda.
Uso um Laptop LG R590 i3, 4 RAM, 500 HD só com o Ubuntu 12.04 (e alguns aplicativos). A distro foi instalada a partir de um pendrive inicializável.

Desde já, muito obrigado.
PS: Após o último "sudo apt-get upgrade" e "sudo apt-get update" obtive os seguintes resultados:

UPGRADE
Lendo listas de pacotes... Pronto
Construindo árvore de dependências      
Lendo informação de estado... Pronto
0 pacotes atualizados, 0 pacotes novos instalados, 0 a serem removidos e 0 não atualizados.

UPDATE (resumi alguma mensagens com: início com erro... / fim com erro...)

Voce tem uma boa salada de repositórios....

Remova inicialmente todos os repositórios relacionados a "gusty" e mantenha todos os "precise"

Poste aqui o resultado em terminal de

Prezado clockworklinux.

Criei apenas um tópico, porém dividido em duas partes.
Não foi posto em apenas uma parte por falta de capacidade do módulo de edição do fórum.
Por favor, me ajude, me explique como burlar o limite de caracteres.
Seu comentário não ajudou a sanar meu problema.
Comentários críticos sem apresentação de soluções não são produtivos.
De qualquer maneira, muito obrigado pela atenção.

Abraço!

Criei apenas um tópico, porém dividido em duas partes.

Não foi bem assim, voce criou dois topicos, ao invés de criar uma segunda mensagem no primeiro topico criado. Eu uni os dois e alterei o titulo para adequar tudo às regras do forum

Da forma de publicação das mensagens

8. Não são permitidas mensagens/títulos:

XII - Que possuam título que não esclareçam o contexto da mensagem.

XVI - Com conteúdo duplicado.

Por favor, me ajude, me explique como burlar o limite de caracteres.

Isto não é possivel de ser feito neste forum.

Olá, Tota.
Removi as entradas com o termo "gutsy" e o comando "sudo apt-get update" gerou o relatório abaixo.
Obrigado.

Mano eu estava com o mesmo problema e seguindo a dica do platão eu resolvi, tenta ai...
http://ubuntuforum-br.org/index.php/topic,95441.msg524718.html#msg524718

[leodok]

Olá, acabei de fazer uma atualização do Kernel e outras também, quando reienicei o pc, veio com o tamanho de tela desconfigurado, olhei na configuração do monitor e está correta, o sistema usava o driver da nvidea e agora tem uma mensagem para eu executa-lo, mas não sei como,  não sei o que fazer, agradeço alguma ajuda desde já

[jkmsjq]

Olá, acabei de fazer uma atualização do Kernel e outras também [...] e agora tem uma mensagem para eu executa-lo [...]

Se você postasse na íntegra a mensagem que aparece não acha que ficaria mais fácil de ser ajudado aqui no fórum pelos membros...?!?!?

[leodok]

Na verdade só aparece uma mensagem quando tento acessar o driver da nvidea: "You do not appear to be using the NVIDIA X driver.  Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server."

[jkmsjq]

Na verdade só aparece uma mensagem quando tento acessar o driver da nvidea: "You do not appear to be using the NVIDIA X driver.  Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server."

No Terminal (Ctrl + Alt + T) digite:

Código: [Selecionar]

sudo nvidia-xconfig
Dê <Enter> e digite a sua senha, terminando o processo no mesmo Terminal digite:

Código: [Selecionar]

sudo reboot now
Dê <Enter> e digite a sua senha.

P.S.: Se você observar a própria mensagem trás a solução do problema

"(just run `nvidia-xconfig` as root), and restart the X server."

[leodok]

consegui resolver de outra forma, fui em configurações - drivers adicionais - ativar.
Obrigado!
