erro na actualização do ubuntu 16.04

José Leitão · 25 de Outubro de 2016, 17:53

boa noite
tenho tentado fazer a actualização do ubuntu 16.04 a partir do "acerca deste computador" mas depois de carregar na tecla para actualizar aparece-me sempre esta mensagem:

"falha ao transferir as informações do repositório
verifique a sua ligação à internet"

o que devo fazer?
obrigado desde já

Olá,

A primeira coisa é saber se você tem "proxy" na sua rede.

Claro, se sua conexão esta ativa como pede o erro e então abra um terminal e comande:

Código Selecionar

sudo apt update

Copie a saída do terminal e cole aqui.

Veja no final que tenho o repositório extras.ubuntu.com habilitado porém se você acessar o repo irá notar que o seu ubuntu 16.04 (Xenial) não tem esse repositório, vaja em: http://extras.ubuntu.com/ubuntu/dists/

Ou clique na imagem para ver

Tentando adivinhar aqui uma possível resolução é só editar o arquivo sources.list e comantar a linha referente ao repositório

Se você usa Unity siga a sequência:
- Abra o terminal e comande:

Código Selecionar

sudo gedit /etc/aptsources.list
- Lá procure pela linha e comanete na frente da linha com # salve e feche o editor não o terminal

Se usa kde, também no terminal:

Código Selecionar

sudo kwrite /etc/apt/sources.list
- Faça o mesmo procedimento comentar a linha, salve e feche o editor não o terminal

Depois dê um sudo apt update

E veja se desaparecem os erros

Boa sorte!

bom dia
o comando deu-me isto

jose@jose-A6JC:~$ cat/etc/apt/sources.list
bash: cat/etc/apt/sources.list: Ficheiro ou directoria inexistente
jose@jose-A6JC:~$ ^C
jose@jose-A6JC:~$

Tota · 27 de Outubro de 2016, 09:01

Amigo,

Entre "cat" e "/etc" existe um espaço em branco

cat/etc/apt/sources.list é diferente de

cat /etc/apt/sources.list

Já que cat é um comando, e /etc/apt/sources.list é o local onde o arquivo sources.list se encontra.

José Leitão · 28 de Outubro de 2016, 08:20

Boa tarde
Fiz tudo conforme descreveu e o comando já me diz que o sistema está actualizado. Penso que o problema ficou resolvido.
Muito obrigado pela atenção
