Olá KamiKase,

Pode partilhar aqui o erro que lhe dá ao tentar actualizar via terminal? É que assim à primeira vista, parece não haver nada de errado, mas sem mais informação, fica-se às aranhas...

Olá Luís Cardoso, pelo terminal aparece o seguinte:

Segundo a sua resposta, está a querer actualizar o Ubuntu para a nova versão... Para a simples actualização de aplicações, dentro da mesma versão do Ubuntu, então usa-se o seguinte comando:

sudo apt-get update && sudo apt-get upgrade

Em caso de bibliotecas novas que obriguem a remoção e/ou instalação de pacotes extra, então será o seguinte comando:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

Se o que pretende, é mesmo fazer uma actualização do Ubuntu 12.04 para o mais actual, então tem mesmo de ver o que se passa nos registos que o apt-get lhe indicou:

• /var/log/dist-upgrade/main.log
• /var/log/dist-upgrade/apt.log

Ok. Obrigado, Luis Cardoso.
